- Abstract
  
  A manifold submetry is a map from a Riemannian manifold to a metric space, with smooth and equidistant fibers. Such objects appear in the literature in relation to rigidity phenomena, especially in the context of non-negative sectional curvature. In the past few years, it was shown that there is a one-to-one correspondence between manifold submetries from spheres and certain algebras of polynomials called Laplacian algebras, and through this correspondence a dictionary has been created between geometric properties of manifold submetries and algebraic properties of the corresponding algebra. In this talk we will survey these results, and discuss recent generalizations of these results to compact symmetric spaces and normal homogeneous spaces.

- Abstract
  
  We examine long-dated asset valuation under systematic and idiosyncratic risk, driven by extreme trajectories. By introducing the zero-Theta hedge contract, a negative-Delta derivative security with a maturity-independent price, we study investor attitudes toward systematic long-run crashes. Declining expected payoff with maturity signal strong crash aversion. The contract aids in decomposing the stochastic discount factor, shedding light on long-run crash risk premia. Even for volatile assets whose price comes from idiosyncratic rallies, systematic long-run crashes remain central to long-run risk valuation.

- Abstract
  
  This presentation addresses the challenges and solutions associated with mixed-dimensional problems on non-matching grids, with a perspective towards exascale computing. Many physical phenomena involve coupled partial differential equations (PDEs) defined on domains of heterogeneous dimensions, leading to non-matching coupling at the interfaces. To tackle these problems, the reduced Lagrange multiplier method [2] provides a general mathematical framework for analysis and approximation. This approach sheds light on the stability, well-posedness, and error associated with dimensionality reduction, but requires the efficient solution of saddle point problems involving non-matching discretizations.
  For the efficient numerical solution of the resulting large-scale systems, particularly on complex geometries like vascular networks embedded in biological tissues [1], we borrow a technique that was developed for non-nested multigrid methods, which offer the required flexibility by allowing the exchange of information between arbitrarily overlapping and distributed grid hierarchies with a matrix-free implementation [3], and we developed augmented Lagrangian-based preconditioners that offer optimal and scalable solutions [4].
  The continued development of such robust and scalable algorithms within high-performance finite element libraries like deal.II is crucial for tackling these challenging problems at the exascale.

  We discuss a nonlocal fractional problem that serves as a nonlocal counterpart of the classical problem of functions of least gradient. We show how we obtain the existence of minimizers by using their connection to nonlocal minimal sets. Additionally, we discuss the continuity of these minimizers and a weak formulation of the problem.

- Abstract
  
  Every simple finite graph G has an associated Lovász-Saks-Schrijver ring \(R_G(d)\) that is related to the d-dimensional orthogonal representations of \(G\). The study of \(R_G(d)\) lies at the intersection between algebraic geometry, commutative algebra, and combinatorics. We find a link between algebraic properties, such as factoriality, of \(R_G(d)\) and combinatorial invariants of the graph \(G\). In particular, we prove that if \(d \geq pmd(G)+k(G)+1\), then \(R_G(d)\) is UFD. Here, \(pmd(G)\) is the positive matching decomposition number of \(G\) and \(k(G)\) is its degeneracy number.

- Abstract
  
  In recent years, along with the increase in the size and complexity of computational models, the scenario of mixed-dimensional (e.g., 2D-1D or 3D-2D, and in general HighD-LowD) coupling has drawn a lot of attention. Fields of application where this scenario is of special interest include, among others, (a) blood-flow analysis, (b) hydrological and geophysical flow models, and (c) elastic structures. In this talk we will review and discuss the application of several coupling schemes to time-dependent wave problems governed by the scalar wave equation and by the equations of elastodynamics.
  After providing the motivation for mixed-dimensional modeling, we will consider the hybrid problem at the continuous level. We will discuss the appropriate interface conditions and prove the well-posedness of the hybrid problem. Among the coupling methods for mixed-dimensional models, we will discuss the Panasenko method, the Nitsche method and two versions of the Dirichlet-to-Neumann (DtN) method. The various methods differ in the way they implement the coupling conditions. We will also discuss the appropriate placement of the HighD-LowD interface, and how this can be estimated a priori and a posteriori. The hybrid model is discretized by the finite element method.
  A special challenge is the attack of elastic problems involving out-of-plane bending. The difficulty lies in the fact that there is a mismatch in the type of unknown variables between the HighD and LowD models, and that there is a significant difference between the types of differential equations and between the types of finite elements (C0 vs. C1) used in each part of the problem. We will present an appropriate coupling approach for such problems.
  We will show the results of some numerical experiments using the various methods, and will compare between them in accuracy and 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.

- 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.

Abstract

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.
