- Aula Seminari III Piano
- Abstract
  
  Whole-brain neural mass models can effectively simulate neural activity, however the elevated model complexity of some implementations might hinder their translation to clinical practice, e.g. for digital twin applications. In this talk we will talk about different strategies to choose the optimal level of complexity and critically evaluate potential added benefit of more sophisticated heterogeneous models. These results might facilitate the translation of models to clinical applications with minimally required model complexity, while maintaining the same accuracy for predictions.

Monolithic hp Space-Time Multigrid Preconditioning for a Newton-Krylov Solver for Space-Time FEM applied to Navier-Stokes Equations
Friday, 5 December 2025 at 11:00
Aula Saleri
Abstract

We present a monolithic hp space-time multigrid method for tensor-product space-time finite element discretizations of the incompressible Navier-Stokes equations. The formulation employs inf-sup stable velocity-pressure pairs in space, a discontinuous Galerkin discretization in time, and combined geometric and polynomial coarsening in both space and time. Nonlinearity due to the convective term is treated by Newton linearization, and the resulting space-time systems are solved by GMRES preconditioned with an hp space-time multigrid method in a matrix-free deal.II implementation using a space-time Vanka-type smoother for the velocity-pressure coupling. The tensor-product structure enables efficient sum-factorization for residual and Jacobian evaluation, and numerical experiments show mesh-independent convergence and robust performance across a range of flow regimes.

- Abstract
  
  Recent studies have extended the theory of affine processes to the stochastic Volterra equations framework. In this talk, I will describe how the theory of polynomial processes extends to the Volterra setting. In particular, I will explain the moment formula and an interesting stochastic invariance result in this context. Potential applications to fractional volatility models will be discussed.

- Aula Seminari III piano
- Abstract
  
  The numbers of flags of different ranks of an Eulerian poset are subject to a set of linear relations which have been described by Bayer and Billera. Fine showed that these relations are equivalent to the existence of a certain polynomial in two non-commutative variables, called the cd-index. The coefficients of such polynomial have been proved to be nonnegative for specific families of posets, hence revealing inequalities among the numbers of flags of such objects. In our work we show that it is possible to extend the definition of the cd-index from Eulerian to semi-Eulerian posets by a small modification of the flag f-polynomial. When the poset is simplicial, we show that a formula due to Stanley continues to hold in the semi-Eulerian setting. Our main result shows that the coefficients of the cd-index of a semi-Eulerian Buchsbaum simplicial poset are nonnegative, hence confirming a conjecture of Novik. This is joint work with Martina Juhnke and José Samper.

- Abstract
  
  In questo incontro racconteremo gli anni forse meno noti della vita di Niccolò Tartaglia, quelli che seguirono la diatriba con Gerolamo Cardano.
  
  Tra il marzo del 1548 e l'ottobre del 1549, Tartaglia fece infatti ritorno a Brescia, sua città di origine, invitato da alcuni importanti personaggi per tenere delle lezioni sulla geometria di Euclide. Quello che doveva essere un ritorno trionfale nella sua città si rivelò invece essere un vero incubo per Tartaglia: mancati pagamenti, scomodi viaggi nella provincia, ospiti indesiderati a casa e, se ciò non bastasse, il cimento reale con Ludovico Ferrari a Milano. Tartaglia raccontò queste sue disavventure nella "Travagliata Inventione" e nel "General Trattato".
  
  Il racconto di queste vicende ci permetterà di approfondire anche l'opera del matematico bresciano, con particolare attenzione ai suoi contributi riguardanti la risoluzione algebrica delle equazioni di terzo grado.

- Abstract
  
  Exploring Math è il titolo di un libro che raccoglie l’esperienza del La.M.Po. (Laboratorio di Matematica del Politecnico di Torino) attraverso la descrizione di nove attività di laboratorio, inizialmente pensate per il primo anno di università e facilmente adattabili alla scuola secondaria. Queste attività sono state ideate per stimolare l’interesse per la matematica e per incoraggiarne lo studio: rendono la classe attiva mettendo al centro oggetti concreti e problemi reali. Pensiamo al problema di tracciare curve nel piano: non riguarda solo i matematici, ma anche, ad esempio, gli ingegneri meccanici e i costruttori. Questo è lo spunto per discutere di meccanismi che tracciano curve, interpretate come curve parametriche. Parleremo in particolare di come tracciare una retta. Non è facile come sembra.

- Abstract
  
  In questo seminario si esploreranno alcuni aspetti applicativi della Teoria dei Grafi e dell'Ottimizzazione Combinatoria, due settori della Matematica che hanno avuto un grande sviluppo negli ultimi decenni grazie alla loro capacità di modellizzare e risolvere problemi
  reali. L'intervento, che non richiede prerequisiti specifici, avrà un taglio divulgativo e sarà ricco di esempi per mostrare come la matematica sia fondamentale nel nostro quotidiano.
  
  Nella parte introduttiva si mostreranno appunto esempi concreti di utilizzo dei grafi in ambiti diversi: dalle neuroscienze per lo studio di malattie degenerative quali l'Alzheimer, allo studio delle relazioni tra utenti di un social network. Poi l'attenzione si sposterà sul settore dei trasporti, ambito in cui la teoria dei grafi trova grandi applicazioni. In particolare, verrà spiegato, in modo semplice e intuitivo, l'algoritmo di Djikstra alla base dei navigatori GPS, facendo alcuni richiami sugli algoritmi e ricordando figure fondamentali dal punto di vista storico quali Abu Ja'far Muhammad ibn Musa al-Khwarizmi e Ada Lovelace.

Abstract

In questo seminario saranno discussi i risultati di recenti studi mirati a investigare potenzialità e criticità connesse all’uso dell’IA generativa come strumento a supporto dei processi metacognitivi nella risoluzione di problemi matematici. Gli studi condotti hanno riguardato, in particolare, l’uso di GPT4o, da parte di studenti del biennio della scuola secondaria di II grado, per affrontare problemi che coinvolgono processi di esplorazione in ambito aritmetico, lo sviluppo di congetture e la costruzione di dimostrazioni attraverso l’uso del linguaggio algebrico.
A partire dalla riflessione sui principali schemi d’uso sviluppati dagli studenti nel corso della loro interazione con GPT4o e sulle interpretazioni che gli studenti danno dei processi di genesi strumentale che li vedono protagonisti, si evidenzieranno elementi di criticità caratterizzanti l’interazione tra utenti umani e IA generativa. Si concluderà proponendo spunti sul ruolo che i docenti possono svolgere nel supportare gli studenti nell’adottare un approccio critico e riflessivo all’uso dell’IA generativa nel problem solving matematico.

Assessing Monotone Dependence

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 covariate $X$. 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 case studies, we assess progress in artificial intelligence (AI) based weather prediction and evaluate methods of uncertainty quantification for the output of large language models. The talk is based on joint work with Eva-Maria Walz and Andreas Eberl.

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.
