- Abstract
  
  La transizione dalla scuola secondaria all’università rappresenta un nodo critico riconosciuto a livello internazionale, in particolare per la matematica. Le difficoltà incontrate dagli studenti nei primi anni universitari vengono spesso attribuite a una preparazione di base insufficiente, ma resta aperta la domanda su cosa si intenda effettivamente per “adeguata preparazione matematica” e su come essa possa essere valutata.
  Nel seminario cercheremo di delineare alcuni aspetti del fenomeno e presenteremo risultati di ricerche sulla transizione scuola–università, che permettono di enucleare i diversi fattori che incidono sul fenomeno, mettendo anche a confronto le aspettative dei docenti di scuola e di quelli universitari. Discuteremo inoltre, in questo quadro, il possibile contributo del Piano Lauree Scientifiche.

- Abstract
  
  The classification of complete 3-manifolds with nonnegative Ricci curvature had been an open problem since the early 1980s and it was finally settled by G. Liu in 2011 using minimal surfaces methods. In this talk I will discuss a new approach to this classification problem, based on two results of independent interest that hold in any dimension: a sharp rigidity theorem for the first Betti number and a vanishing theorem for the simplicial volume. Based on joint work with Alessandro Cucinotta and Mattia Magnabosco.

- Abstract
  
  We consider non-negative solutions, possibly unbounded, to the semilinear equation $-\Delta u=f(u)$ in the upper half-space $R^N_+$ and we prove new one-dimensional symmetry results. Some Liouville-type theorems are also proven in the case of differential inequalities in $R^N_+$, even without imposing any boundary condition. Although subject to dimensional restrictions, our results apply to a broad family of functions $f$. In particular, they apply to all non-negative function $f$ that behaves at least linearly at infinity.

Assessing Monotone Dependence - with Applications to Weather Prediction
Giovedì 5 marzo 2026 alle ore 14:00
Aula Consiglio - VII piano
Abstract

The assessment of monotone dependence between random variables $X$ and $Y$ is a classical problem in statistics and a gamut of application domains. Consequently, researchers have sought measures of association that are invariant under strictly increasing transformations of the margins, with the extant literature being splintered. Rank correlation coefficients, such as Spearman's rho and Kendall's tau, have been studied at great length in the statistical literature, mostly under the assumption that $X$ and $Y$ are continuous. In the case of a dichotomous outcome $Y$, receiver operating characteristic (ROC) analysis and the asymmetric area under the ROC curve (AUC) measure are used to assess monotone dependence of $Y$ on a predictor $X$. In this talk I demonstrate that the two thus far disconnected strands of literature can be unified and bridged, by developing common population level theory, common estimators, and common tests that apply to all types of linearly ordered outcomes. In a case study, we assess recent progress in artificial intelligence based weather prediction (AIWP) versus traditional numerical weather prediction (NWP). The talk is based on joint work with Eva-Maria Walz and Andreas Eberl. This initiative is part of the “Ph.D. 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 Ph.D. students, followed by meetings with the speaker to discuss and go into detail on the topics presented during the talk.

- Abstract
  
  After a brief introduction to the Wasserstein and Hellinger-Kantorovich distances on the space of (probability) measures, we discuss two approaches to the definition of differentiable functions on spaces of measures. Provided a suitable (and in a way canonical) reference measure is chosen, we show that the two approaches coincide. Finally, we discuss some possible applications such as the study of HJB equations and stochastic processes on spaces of measures.

- Venerdì 6 marzo 2026 alle ore 14:00
- Aula Saleri
- Abstract
  
  The ever-increasing complexity of real-world applications has raised important challenges in the search for accurate and efficient numerical methods for solving partial differential equations. In particular, we are interested in modelling light propagation in the human cornea, where curvature and microstructural organisation have a strong influence on physical behaviour and pose significant challenges for the accurate numerical simulation of these phenomena. To address these challenges, we present a high-order numerical approach based on discontinuous Galerkin methods combined with a polynomial reconstruction strategy. This approach effectively handles curved boundary domains without relying on curved meshes and preserves the optimal convergence order that is often lost with standard polygonal approximations. The proposed method is supported by theoretical analysis and validated through numerical tests.

- Abstract
  
  A survey of reservoir computing (RC) as a dynamical framework for learning, classification, prediction, and data analysis is presented. Three reservoir architectures are considered: the echo-state network, a FitzHugh-Nagumo excitable network, and a transformer-inspired reservoir, which are implemented to perform tasks of increasing complexity: learning logical functions, physics-informed solving of the damped harmonic oscillator (including autonomous rollout), image classification with an untrained convolutional front-end, and multi-input RC for CLIP-style language-image pre-training.

Modelling for understanding – old problems and new challenges for the energy transition

Sala Consiglio, Dipartimento di Matematica, Politecnico di Milano
Abstract

Geoenergy applications beyond hydrocarbons will play an essential role in accelerating the energy transition: Carbon capture and storage (CCS) is one of the most important approaches to mitigate CO2 emissions; approximately 50% of the energy consumed in the northern hemisphere is needed for heating and cooling, and the expanded use of geothermal energy could lead to significant CO2 reduction; the development of a hydrogen economy for power, transport, and production will rely on intermittent hydrogen storage in geological formations or salt caverns.

All these low-carbon geoenergy applications need bespoke reservoir modelling approaches to estimate available pore volumes for storage, capture how fluids with vastly different properties (e.g. hydrogen vs. hot water) interact with multi-scale geological heterogeneities, and quantify possible operational risks (e.g., early breakthrough of cold water during geothermal energy extraction) while accounting for the uncertainties inherent to geological formations.

This talk will explore how mathematical techniques could be adapted to overcome limitations in existing modelling approaches for low-carbon geoenergy applications. Such new modelling approaches should help to ensure that we design meaningful reservoir models that can provide reservoir performance forecasts with reliable uncertainty bounds, which are needed for new geoenergy applications to advance our transition to a low-carbon energy future.

- Indam workshop: geometry of severi varieties and hurwitz spaces
- organizzatori
  K. Christ, S. Molcho, S. Torelli
- Hurwitz spaces and Severi varieties are among the most classical spaces studied in algebraic geometry, going back to the beginnings of modern algebraic geometry in the second half of the 19th century. Since that time, they have remained central objects in the theory of algebraic curves. Though very classical objects, new techniques have in recent years been used to find answers to old questions, and to establish many new connections. The aim of the workshop is to bring together experts in these various approaches in order to explore further applications and possible synergies. Particular areas of focus are the global geometry of Severi varieties and Hurwitz spaces, as well as relations to Brill Noether theory and to the moduli space of curves and its subloci.
