SMF: François Delarue at Milano-Bicocca (Apr 18, 2024)
by Maurizia Rossi 10 Apr '24

10 Apr '24

Dear colleagues, I am glad to announce the following talk which is part of the *"Seminario Matematico e Fisico di Milano" *activities. Speaker: *François Delarue* (Univ. Côte d'Azur) Title:* Mean field control and games. Some prospects. * *Time and place:* April 18, 2024 - 2:00pm-3:00pm - building U5/room 3014 Dept. of Mathematics and Applications, Univ. Milano-Bicocca. *Abstract:* I will first give a brief overview of the notion of mean-field control and games. In particular, I will focus on the Eulerian formulation, through the notion of master equation, which is a nonlinear PDE on the space of probability measures. This PDE is notoriously difficult to solve, at least in a classical sense, except in cases presenting a form of convexity or monotonicity in the argument of the measure. I will then present two problems outside the convex/monotonic framework: (i) non-convex mean-field control problems and their particle approximation, (ii) mean-field games subject to certain non-standard forms of common noise. Best wishes, Maurizia Rossi -- Maurizia Rossi Dipartimento di Matematica e Applicazioni Università degli Studi di Milano-Bicocca https://mauriziarossi.wordpress.com

An afternoon on the spectral theory of pseudo-differential operators
by Enrico Scalas 08 Apr '24

08 Apr '24

Dear Colleagues, On 9 april 2024 starting from 14:00 in room 34, 4th floor of the Department of Statistical Sciences, Sapienza University of Rome, (building CU002), two seminars on non-local operators will take place. Here is the program. Please feel free to inform interested people. Best regards, Enrico Scalas -- 14:00 - 15:00 Atsuhide Ishida (Tokyo University of Science, Tokyo, Japan) Mourre inequality for non-local Schrödinger operators We consider the Mourre inequality for the following self-adjoint operator $H=\Psi(-\Delta/2)+V$ acting on $L^2(\mathbb{R}^d)$, where $\Psi: [0,\infty)\rightarrow\mathbb{R}$ is an increasing function, $\Delta$ is the Laplacian and $V: \mathbb{R}^d\rightarrow\mathbb{R}$ is an interaction potential. Mourre inequality immediately yields the discreteness and finite multiplicity of the eigenvalues. Moreover, the Mourre inequality together with the limiting absorption principle can be used to show absence of the singular continuous spectrum. In addition, Mourre inequality is also used for the proof of the minimal velocity estimate that plays an important role in scattering theory. In this talk, we report that Mourre inequality holds under a general $\Psi$ and $V$ by choosing the conjugate operator $A=(p \cdot x + x \cdot p)/2$ with $p= - i \nabla$, and that the discreteness and finite multiplicity of the eigenvalues hold. This talk is a joint work with J. Lőrinczi (Alfred Rényi Institute) and I. Sasaki (Shinshu University). 15:00 - 15:30 Coffee break 15:30 - 16:30 József Lőrinczi (Alfred Rényi Institute, Budapest, Hungary) Embedded eigenvalues for a class of non-local Schrödinger operators Generally, the spectrum of a non-local Schrödinger operator may be rather intricate, even when they are self-adjoint operators. In this talk I plan to discuss some explicit cases when positive or zero eigenvalues occur, and also address the problem more generally, aiming to describe potentials which can give rise to zero eigenvalues for massive or massless (fractional) relativistic Schrodinger operators. If time permits, I intend to explain how random processes with jumps can be used to analyse such properties. 16:30 - 18:00 Discussion time

Seminario PRISMA oggi
by Francesco Caravenna 08 Apr '24

08 Apr '24

Seminari on-line del gruppo UMI - PRISMA (http://www.umi-prisma.polito.it/ <http://www.umi-prisma.polito.it/>) Ricordiamo che oggi, lunedì 8 aprile 2024, Emanuela Sasso (Università di Genova) e Federico Girotti (Politecnico di Milano) ci parleranno di Semigruppi quantistici markoviani: decoerenza, ricorrenza e accessibilità con il seguente orario: 16:00 Primo seminario 16:30 Pausa e discussione 16:45 Secondo seminario 17:15 Conclusione e discussione Trovate di seguito il riassunto. I seminari verranno trasmessi via Zoom al seguente link: https://uniroma1.zoom.us/j/82939128330 <https://uniroma1.zoom.us/j/82939128330> Meeting ID: 829 3912 8330 Vi aspettiamo numerosi, Valentina Cammarota e Francesco Caravenna %%%%%%%%%%%%%%%%%%%%%%%%%%%% RELATORI: Emanuela Sasso (Università di Genova) e Federico Girotti (Politecnico di Milano) TITOLO: Semigruppi quantistici markoviani: decoerenza, ricorrenza e accessibilità RIASSUNTO: I semigruppi markoviani quantistici sono essenzialmente semigruppi di operatori positivi su algebre di operatori con le opportune proprietà di continuità e che rafforzano la positività. Appaiono nella letteratura fisica e fisico-matematica alla fine degli anni '60 con il nome di semigruppi dinamici quantistici nella modellizzazione e nell'analisi dei sistemi aperti in meccanica quantistica. Tuttavia, dal punto di vista matematico, costituiscono la naturale generalizzazione dei semigruppi markoviani classici, infatti questi ultimi sono semigruppi di operatori definiti su un'algebra di funzioni, cioè un'algebra di operatori che commutano tra loro. Il modo più naturale per descrivere un sistema quantistico è un’algebra di Von Neumann e la sua evoluzione come una famiglia di operatori debole*-continui, che formino un semigruppo e che abbiano la proprietà di markovianità. Se il sistema è chiuso allora la sua evoluzione è reversibile, altrimenti se interagisce con l’ambiente allora ci potrebbe essere una parte diffusiva. In Fisica, si parla di “decoerenza” quando solo una parte del sistema evolve in maniera automorfica (l’algebra priva di decoerenza, appunto) e una parte “scompare” per tempi lunghi. La nostra ricerca si è focalizzata a lungo su quale definizione di decoerenza sia più adatta e se è possibile trovare condizioni necessarie e sufficienti per il suo verificarsi. Nello studio dei processi (semigruppi) di Markov classici sono fondamentali le nozioni di ricorrenza e comunicazione tra insiemi di stati; mostreremo come questi concetti siano stati generalizzati nel caso noncommutativo e discuteremo alcune delle loro proprietà e relazioni. Particolare attenzione sarà dato al caso in cui l’algebra su cui agisce il semigruppo sia l’insieme di tutti gli operatori lineari limitati che agiscono su uno spazio di Hilbert. %%%%%%%%%%%%%%%%%%%%%%%%%%%% I seminari PRISMA hanno un formato di "colloquium", per creare un'occasione di scambio e discussione con tutta la comunità dei probabilisti e statistici italiani. Ogni giornata comprende due relatori che tengono due seminari di 30 minuti strettamente connessi, per presentare alla comunità una prospettiva sul proprio ambito di ricerca. Da quest'anno le registrazioni dei seminari vengono pubblicate sul canale YouTube dell'UMI: https://www.youtube.com/playlist?list=PLmySpc-jrtAMq84VH71evyqPc1hl6eEQb %%%%%%%%%%%%%%%%%%%%%%%%%%%%
