Seminario Lukas Wessels a Milano-Bicocca
by Federica Masiero 04 Jul '25

04 Jul '25

Buongiorno segnalo il seguente seminario *Martedì 8 Luglio 2025, ore 11:30.* Aula 3014, Edificio U5, terzo piano, Dipartimento di Matematica e Applicazioni, via Cozzi 55, Università di Milano-Bicocca *Speaker*: Lukas Wessels, Georgia Institute of Technology, Atlanta *Title*: Necessary and Sufficient Conditions for Optimal Control of Semilinear SPDEs *Abstract:* In this talk, we consider a finite-horizon optimal control problem of stochastic reaction-diffusion equations. First we apply the spike variation method which relies on introducing the first and second order adjoint state. We give a novel characterization of the second order adjoint state as the solution to a backward SPDE. Using this representation, we prove the maximum principle for controlled SPDEs. As another application of our characterization of the second order adjoint state, we derive additional necessary optimality conditions in terms of the value function. These results generalize a classical relationship between the adjoint states and the derivatives of the value function to the case of viscosity differentials. The last part of the talk is devoted to sufficient optimality conditions. We show how the necessary conditions lead us directly to a non-smooth version of the classical verification theorem in the framework of viscosity solutions. This talk is based on joint works with Wilhelm Stannat. -- Federica Masiero Dipartimento di Matematica e Applicazioni, Università di Milano Bicocca, Edificio U5 via Roberto Cozzi, 55, 20126 Milano

IAMG Distinguished Lecture di Jeff Boisvert presso Politecnico di Milano
by Alessandra Menafoglio 03 Jul '25

03 Jul '25

Si avvisa che in data 11-07-2025, alle ore 10:00 presso il Politecnico di Milano, Edificio 14 (Via Bonardi 9), in Aula B.5.3 (quinto piano), nell’ambito delle attività del MOX e della IAMG Distinguished Lecture Series, si svolgerà il seguente seminario: Jeff Boisvert — University of Alberta e IAMG Distinguished Lecturer for 2025 Titolo: The Future of Machine Learning and Model Validation in the Earth Sciences: The Good, the Bad, and the Ugly Abstract: The earth sciences are being transformed by advances in machine learning (ML) and artificial intelligence. From optimizing mineral estimation and hydrocarbon production to improving wildfire prediction and management, these methods offer exciting opportunities for modeling and decision-making. However, these advances bring challenges with model validation, which is critical for ensuring that predictions are robust, reasonable, and actionable. This lecture will delve into the evolving role of ML in the mining, hydrocarbon, or wildfire industry, highlighting successes, pitfalls, and future prospects. "The Good" will explore case studies and implementations where ML has significantly improved modeling, decision making, and inference. "The Bad" will examine common pitfalls, including data biases, overfitting, and the misuse of algorithms without understanding domain constraints. Finally, "The Ugly" will confront the ethical and operational risks posed by poorly validated models, emphasizing the importance of transparency and domain experts. This lecture will not only focus on ML methods, but will also consider how to validate all types of earth science models including estimates, simulations, and decision making. We will discuss best practices for integrating ML models into traditional workflows while addressing the complexities of model validation. The seminar is part of the IAMG Distinguished Lecture Series, which is aimed to highlight the critical role of mathematics and statistics in addressing key challenges in the geosciences.

Seminar presented by Marta Leocata - Applications of Probability to Economics
by Enrico Scalas 24 Jun '25

24 Jun '25

Dear colleagues, (With apologies for cross-posting) On 26 June 2025 at 2pm (CET) Marta Leocata (LUISS Guido Carli, Department of AI, Data and Decision Sciences) will present an online seminar whose title is: Two applications of multi-agent models in economic and social systems Abstract: In this talk, we present an overview of mathematical models that capture the behavior of myopic agents—who rely on short-term, local information in their decision-making—and strategic agents, who consider the long-term consequences of their actions within interactive environments. These concepts will be illustrated through two applications in economic and social contexts: a multi-agent model for the co-evolution of preferences and actions in the emergence of social norms (joint work with Michele Aleandri, LUISS, and Laura Marcon, CNR), and a Mean Field Game approach to the Emission Trading System (joint work with Giulia Livieri, LSE, and Gianmarco Del Sarto, TU Darmstadt). The seminar link is: https://uniroma1.zoom.us/j/87022289921 This is the first seminar of a series of three seminars organised by UMI-PRISMA on the Applications of Probability to Economics in preparation to the 2025 Summer School of Mathematics for Economic and Social Sciences: https://indico.sns.it/event/105/overview The next seminars will be: on 10 July 2025, Annamaria Olivieri, (University of Parma (Italy), Department of Economics and Management), Modelling Stochastic Mortality for Life Insurance Applications on 17 July 2025, Sara Merino Aceituno (Faculty of Mathematics, University of Vienna, Austria), Large particle limit for jump processes Everybody is welcome to join these seminars!
