Spectral large deviations of sparse random matrices
Ella HIESMAYR (ENS Lyon)
Abstract: In this talk we consider the adjacency matrix of Erdős–Rényi graphs with constant average degree, that are equipped with i.i.d. edge weights. We determine [...]

Statistical properties of open dynamical systems
Yaofeng Su (U. Rome Tor Vergata)
In this talk I will talk about some new results for the escape and hitting statistics for various open dynamical systems. This includes : Poisson [...]

Load identification in a plate-beam lattice from interior dynamic data.
Alexandre Kawano (Universidade de São Paulo (Brésil))
In this talk, we address the inverse problem of determining transverse dynamic loads on a clamped plate reinforced by two orthogonal sets of beams. Under [...]

Bootstrap Percolation on Rhombus Tilings
Solène Esnay (I2M)
In this talk, we introduce dynamical (bootstrap) percolation, where a tiling of the plane has each tile independently colored 0 or 1 following a measure [...]

Don't take Math for granted!
Valentin Maestracci (I2M (AMU))
In this highly non technical talk, I'll try to do the (hopefully) healthy exercise of casting doubt on what we take for granted in math! [...]

Partial Markov Categories [LSC]
Mario Román (Oxford)
Partial Markov categories are a careful blend of Markov categories (from categorical probability theory) and cartesian restriction categories (from the algebraic theory of partial computations). [...]

Le théorème de reconstruction stochastique et une EDPS hyperbolique mixte
Carlo BELLINGERI (Institut Elie Cartan, Univ. de Nancy)
Initialement considéré comme un lemme clé dans les structures de régularité, le théorème de reconstruction s'est avéré être un outil analytique très flexible pour étudier [...]

On the higher analytic vectors of $B_e$
Rustam Steingart (ENS Lyon)
The category of $p$-adic representations of $G=G_{Q_p}$ can be viewed as subcategory of the category of equivariant vector bundles on the Fargues-Fontaine curve, obtained by [...]

Extrapolation of Wasserstein geodesics
Gabriele Todeschi (Université Gustave Eiffel (Paris))
Abstract: Extending geodesics in the Wasserstein space, namely the space of probability measures endowed with the quadratic Wasserstein distance, can be useful for designing high [...]

Coalgebraic causal processes [LSC]
Elena Di Lavore (Pisa)
Effectful streams are a coinductive semantic universe for effectful dataflow programs. Under some conditions, effectful streams generalise causal stream functions, which are classically known to [...]

Zero and Nonzero exponents for the twisted Cocycle for IETs and Translation Surfaces
Pedram Safae (École Polytechnique )
I start by giving an introduction to IETs, translation flows, and the notion of renormalization. Then I motivate and define the rather new concept of [...]
Modular curves, an example-based introduction to moduli spaces
Pierre Tchamitchian (I2M (AMU))
Elliptic curves are one of the most studied object by mathematician. They are simple enough to allow us to write down example and work with [...]

Taut foliations from knot diagrams
Diego Santoro (University of Vienna)
Taut foliations have been a classical object of study in 3-manifolds theory. Recently, new interest in them has come from the investigation of the so-called [...]

Probabilistic mixing for the geodesic flow on hyperbolic varieties
Joffrey Mathien (I2M, AMU, CNRS)
For an ergodic dynamical system, the cutoff describes an abrupt transition to equilibrium. Historically introduced by Diaconis, Shahshahani and Aldous for card shuffling and other [...]

Uniqueness of Malliavin-Kontsevich-Suhov measures
Guillaume BAVEREZ (I2M)
Abstract: About 20 years ago, Kontsevich & Suhov conjectured the existence and uniqueness of a family of measures on the set of Jordan curves, characterised [...]

Approximations modales en nano plasmonique et applications à la super localisation
Alice Vanel (Institut Fresnel (Marseille))
Nous présentons des résultats récents sur l'analyse spectrale de l'opérateur intégral singulier associé à l’équation d’ondes. L'opérateur n'est ni compact ni auto-adjoint dans le cas [...]

Alternating hierarchy of subshifts defined by nondeterministic plane-walking automata
Pacôme Perrotin (Universidade Presbiteriana Mackenzie, Brésil)
Plane-walking automata were introduced by Salo & Törma to recognise languages of two-dimensional infinite words (subshifts), the counterpart of 4-way finite automata for two-dimensional finite [...]
