1:31:02 David Mukamel: Steady states and long range correlations in driven systems - Lecture 1 Abstract : In these three lectures steady states and dynamical properties of nonequilibrium systems will be discussed.
Systems driven out of thermal equilibrium often reach a steady state which und...

52:24 Andrea Pulita: An overview on some recent results about p-adic differential equations ... Abstract: I will give an introductory talk on my recent results about p-adic differential equations on Berkovich curves, most of them in collaboration with J. Poineau. This includes the continuity ...
54:58 Vladimir Berkovich: de Rham theorem in non-Archimedean analytic geometry Abstract: In my work in progress on complex analytic vanishing cycles for formal schemes, I have defined integral "etale" cohomology groups of a compact strictly analytic space over the field of La...
54:37 Charles Favre: Explosion of Lyapunov exponents using non-Archimedean geometry Abstract: We consider a meromorphic family of endomorphisms of the complex projective space parameterized by the unit disk, and show that the blow-up of the Lyapunov exponent near the origin is con...
55:26 Tomoyuki Abe: Arithmetic D-modules and existence of crystalline companion Abstract: We will show that there exists a correspondence between smooth l-adic sheaves and overconvergent F-isocrystals over a curve preserving the Frobenius eigenvalues. Moreover, we show the exi...
57:34 Hélène Esnault: D-modules and p-curvatures Abstract: We show relations between rigidity of connections in characteristic 0 and nilpotency of their p-curvatures (a consequence of a conjecture by Simpson and of a generalization of Grothendiec...
1:12:50 Guillaume Fertin : Le problème Graph Motif - Partie 2 Résumé : Le problème Graph Motif est défini comme suit : étant donné un graphe sommet colorié G=(V,E) et un multi-ensemble M de couleurs, déterminer s'il existe une occurrence de M dans G, c'est-à-...

28:48 Cécile Mailler : Processus de Pólya à valeur mesure Résumé : Une urne de Pólya est un processus stochastique décrivant la composition d'une urne contenant des boules de différentes couleurs. L'ensemble des couleurs est usuellement un ensemble fini {...
1:01:41 Sophie Schbath : Une histoire de mots inattendus et de génomes Résumé : Dans une première partie, je présenterai différentes problématiques liées à des statistiques d'occurrences de mots dans des génomes et décortiquerai plus en détail la question de savoir co...
58:18 Juanjo Rué : Random cubic planar graphs revisited Abstract: We analyze random labelled cubic planar graphs according to the uniform distribution. This model was analyzed first by Bodirsky et al. in a paper from 2007. Here we revisit and extend the...
