    • Abstract
      I will present recent work on integer quantum Hall droplets with anisotropic trapping potentials. Using semiclassical methods, we obtain the one-particle energy spectrum and wave functions in the lowest Landau level by deriving and solving a transport equation inspired by standard WKB theory. This shows that energy eigenstates are localized on equipotentials of the trap, generalizing the rotational-symmetric case for isotropic potentials. From these microscopic first-principle considerations, we show that many-body correlations along the droplet's edge are long-ranged, in agreement with low-energy edge modes described by a free chiral conformal field theory in terms of the canonical angle variable of the potential. Comparing our results with the widely used plasma analogy, we show that the latter is unreliable at predicting edge properties of quantum Hall states. This discrepancy arises from a difference in geometries between quantum Hall droplets and plasmas (Coulomb gases): The former are incompressible liquids subject to area-preserving deformations, while the latter are governed by electrostatics and thus involve conformal maps. Consequently, the plasma analogy generally fails at the edge of anisotropic droplets.

    • Abstract
      This talk surveys the problem of characterizing the \(X-\)domains: planar domains \(\Omega\subset\mathbb C\) such that every holomorphic map \(f:\mathbb D\to\mathbb C\) belongs to a given holomorphic function space \(X\) on the unit disk \(\mathbb D\). Classical contributions include characterizations for \(X\) being the Bloch space (Seidel, Walsh, 1942), the space of analytic functions of bounded mean oscillation BMOA (Hayman, Pommerenke, 1978), and the Smirnov class (Ahern, Cohn, 1983).

      The case of Hardy spaces \(H^p\) has remained particularly active. Hansen (1970) introduced the Hardy number of a domain \(\Omega\subset\mathbb C\), defined as the supremum of all \(p>0\) such that \(\operatorname{Hol}(\mathbb D,\Omega)\). Subsequent work, notably by Essén (1981) and Kim and Sugawa (2011), established connections between the Hardy number of a domain and harmonic measure. More relations between the Hardy number of a domain and other potential-theoretic quantities have been encountered recently. The Hardy number of domains with special geometric properties has also been explored, including star-like domains (Hansen, 1971), comb domains (Karafyllia, 2021), and Koenigs domains (Contreras, Cruz-Zamorano, Kourou, Rodr'iguez-Piazza, 2024).

      Karafyllia (2023), building on a previous work with Karamanlis, extended this problem to (weighted) Bergman spaces, introducing the Bergman number of a domain. We will also discuss a close relationship between the Hardy number and the Bergman number of a planar domain, covering recent ideas on this topic obtained in collaboration with Betsakos.

    • Abstract
      A celebrated inequality by Payne relates the first eigenvalue of the Dirichlet Laplacian to the first eigenvalue of the buckling problem. Motivated by the goal of establishing a quantitative version of this inequality, we show that Payne’s original estimate—which is not sharp—can in fact be improved. Our result provides a refined spectral bound and opens the way to further investigations into quantitative enhancements of classical inequalities in spectral theory.

    • Abstract
      Local asymptotic normality is a key concept in mathematical statistics, which underlies the asymptotic achievability of the Cramer-Rao bound and the asymptotic normality of optimal estimators.

      In this presentation, I will review some of the current progress in extending this concept to the field of quantum statistics. In quantum estimation, one is given “quantum data” in the form of a quantum system prepared in a state that depends on an unknown parameter, and would like to estimate the parameter based on “classical data” obtained by measuring the system. This raises the problem of finding optimal measurements which extract maximum amount of information about the parameter.

      Quantum local asymptotic normality (QLAN) shows that in the limit of large “sample size”, certain quantum statistical models can be approximated by simpler Gaussian models where the unknown parameter is encoded linearly in the mean of the canonical variables. This simplification provides a procedures for constructing optimal estimators with normally distributed errors. I will discuss two settings in which QLAN holds: ensembles of identical, independent systems, and quantum Markov chains.

      This initiative is part of the "PhD Lectures" activity of the project "Departments of Excellence 2023-2027" of the Department of Mathematics of Politecnico di Milano. This activity consists of seminars open to PhD students, followed by meetings with the speaker to discuss and go into detail on the topics presented at the talk.

    • Abstract
      Free boundary problems in partial differential equations (PDEs) are a class of mathematical problems in which both the solution to the PDE and the domain on which it is defined must be determined simultaneously, as the region is not known in advance. These problems arise in many physical and engineering contexts, such as fluid dynamics, solid mechanics, and heat conduction. In this talk, we will focus on certain free boundary problems related to thermal insulation, where either the boundary itself must be found, or the presence of an insulating material requires determining its optimal placement in order to minimize heat loss or maximize energy efficiency.

    • Abstract
      We address the well-posedness of weak solutions for a general linear evolution problem on a separable Hilbert space. For this classical problem there is a well-known challenge of obtaining a priori estimates, as a constructed weak solution may not be regular enough to be utilized as a test function. This issue presents an obstacle for obtaining uniqueness and continuous dependence of solutions.
      When formal energy estimates ara available, we provide a general notion of weak solution and, through a straightforward observation, obtain that arbitrary weak solutions have additional time regularity and obey an a priori estimate. This yields weak well-posedness. Our result rests upon a central hypothesis asserting the existence of a "good" Galerkin basis for the construction of a weak solution. A posteriori, a strongly continuous semigroup may be obtained for weak solutions, and by uniqueness, weak and semigroup solutions are equivalent.

    • Abstract
      Liquid crystal elastomers (LCEs) are materials where a nematic liquid crystal is coupled with a rubbery material. When actuated with heat or light, the interaction of the liquid crystal with the rubber creates complex shapes. Thin bodies of LCEs are natural candidates for soft robotics applications. Starting from the classical 3D trace energy formula of Bladon, Warner and Terentjev (1994), we derive a 2D plate theory as the asymptotic limit of the 3D energy using the tools of Gamma-convergence. The resulting bending problem consists of minimizing an energy that is a function of the curvatures of the parameterized surface, subject to a metric constraint. This metric constraint is the leading order behavior that drives large deformations of LCEs. Numerically, we solve this metric constraint by numerical minimization of a formally derived stretching energy with the bending energy serving as a regularization for the discrete problem. We prove that minimizers of the discrete energy converge to zero energy states of the stretching energy in the spirit of Gamma convergence. We solve the discrete minimization problem via an energy stable gradient flow scheme. We present computations showing the geometric effects that arise from liquid crystal defects as well as computations of nonisometric origami, both within and beyond theory. The plate theory derivation is joint work with P. Plucinsky and D. Padilla-Garza and the computational work is joint with R.H. Nochetto and S. Yang.

    • Abstract
      The talk will survey various models of traffic flow, with particular focus on new mathematical problems arising from some of these models. A large literature is currently available on particle models, describing the position of every car in terms of a large number of ODEs, and macroscopic models, where the traffic density is determined by a PDE.
      Vehicular traffic can also be analyzed from the point of view of decision theory. Indeed, daily traffic patterns arise as the outcome of the decisions of a large number of drivers, who choose their departure time and route to destination in an ``optimal" way. Some recent work and open problems will be discussed.

    • Abstract
      We review a method to obtain optimal Poincaré-Hardy inequalities on the hyperbolic spaces by Berchio, Ganguly and Grillo. Then we show how to transfer the basic idea to the discrete setting. This yields optimal Poincaré-Hardy-type inequalities on model graphs which include fast enough growing trees and anti-trees. Moreover, this method yields optimal weights which are larger outside of a ball than the optimal weights constructed via the Fitzsimmons ratio of the square root of the minimal positive Green's function. Joint work with Christian Rose.

    • The goal of this workshop is to gather researchers working in the field of Partial Differential Equations with expertise in nonlocal and nonlinear equations. Among others, one of the simplest mathematical ways to describe many real-world problems is to start from a set of interacting particles, resulting in nonlocal and nonlinear PDEs in the many-particle limit. Despite the past progress in this field, recent discoveries in biology, plasma physics, and data science, among others, shed the lights on new challenges involving nonlocal structures, such as networks or graphs, and highly nonlinear and singular aggregation-diffusion equations. During the workshop we will focus on various mathematical issues in this direction, for instance: micro-macro description of diffusion process, evolutions on graphs, fluxes with nonlinear mobility, fourth-order aggregation-diffusion equations, etc. This workshop is partially funded by the Advanced Grant Nonlocal-CPD: "Nonlocal PDEs for Complex Particle Dynamics: Phase Transitions, Patterns and Synchronization" of the European Research Council Executive Agency (ERC) under the European Union's Horizon 2020 research and innovation programme (grant agreement No. 883363).

    • Abstract
      We present our joint work with many collaborators on multi-physics and multiple scales, with focus on processes in  the Arctic, a vast and complex environment of great current interest, with physical models sharing some (but not all) features with high alpine environments and other cold regions.  Our interest is in robust, accurate and conservative computational schemes for the multi-physics: thermal, flow and mechanical deformation (TpHM) in the snow, ice and soils responding to the forcings from the environment for which the data is sparse. The models account for multiple phases and components and present challenges due to the presence of free boundary e.g. of freezing/thawing/sublimation, strong dependence of constitutive parameters on the micro-physics of TpHM, disparate time scales, and micro- and macro heterogeneity. We show how to build constitutive relationships for Darcy scale models from the first principles at the interface- and pore-scale by a combination of mathematically rigorous theory, practical computational upscaling, and surrogate data science tools. We illustrate with simulations of practical scenarios.

      The finite element method (FEM) is one of the great triumphs of applied mathematics, numerical analysis and software development. Recent developments in sensor and signalling technologies enable the phenomenological study of complex natural and physical systems. The connection between sensor data and FEM has been restricted to solving inverse problems placing unwarranted faith in the fidelity of the mathematical description of the system under study. If one concedes mis-specification between generative reality and the FEM then a framework to systematically characterise this uncertainty is required. This talk will present a statistical construction of the FEM which systematically blends mathematical description with data observations by endowing the Hilbert space of FEM solutions with the additional structure of a Probability Measure.

    • Abstract
      I will discuss the application of compatible finite element methods to large scale atmosphere and ocean simulation. Compatible finite element methods extend Arakawa's “C-grid” finite difference scheme to the finite element world. They are constructed from a discrete de Rham complex, which is a sequence of finite element spaces which are linked by the operators of differential calculus. The use of discrete de Rham complexes to solve partial differential equations is well established, but in this talk I focus on the specifics of dynamical cores for simulating weather, oceans and climate. The most important consequence of the discrete de Rham complex is the Hodge-Helmholtz decomposition, which has been used to exclude the possibility of several types of spurious oscillations from linear equations of geophysical flow. This means that compatible finite element spaces provide a useful framework for building dynamical cores. In this talk I will introduce the main concepts of compatible finite element spaces, and discuss their wave propagation properties. I will then cover a selection of the following topics (depending on recent advances, and interests of the audience): practical application to numerical weather prediction and ocean models, structure preserving methods, and scalable iterative solver techniques.
