Seminar by Marta Maggioni postponed to July 1

The DinAmicI, in solidarity with the #Strike4BlackLives and #ShutDownSTEM movements on June 10, 2020, acknowledge the racism present throughout academia and especially in STEM subjects. In agreement with our speaker Marta Maggioni, whom we sincerely thank, we have decided to reschedule her talk to July 1st. We apologize for any inconvenience and invite everybody  to … Continue reading Seminar by Marta Maggioni postponed to July 1

Speaker: Sunrose Shrestha  (Tufts University, USA) Title: The topology and geometry of random square-tiled surfaces Abstract: A square-tiled surface (STS) is a branched cover of the standard square torus with branching over exactly one point. They are concrete examples of translation surfaces which are an important class of singular flat metrics on 2-manifolds with applications in Teichmüller … Continue reading Sunrose Shrestha (Tufts University, USA)

Speaker: Andreas Knauf (Friedrich-Alexander-Universität Erlangen-Nürnberg, Germany) Title: Asymptotic velocity for scattering particles Abstract: Partly with Jacques Fejoz, Richard Montgomery, Stefan Fleischer and Manuel Quaschner. The past and future of scattering particle systems is partly determined by their asymptotic velocity, that is, the Cesàro limit of the velocity. That this exists for bounded interactions and all initial conditions, is … Continue reading Andreas Knauf (Friedrich-Alexander-Universität Erlangen-Nürnberg, Germany)

Speaker: Marta Maggioni  (Universiteit Leiden, Netherlands) Title: Matching for random systems with an application to minimal weight expansions Abstract: We consider families of skew-product maps, representing systems evolving in discrete time in which, at each time step, one of a number of transformations is chosen according to an i.i.d process and applied. We extend the notion … Continue reading Marta Maggioni (Universiteit Leiden, Netherlands)

Seminar is over: see YouTube recording

Speaker: Françoise Pène  (Université de Bretagne Occidentale, France) Title: Invariance by induction of the asymptotic variance Abstract: It is well known that the integral of an observable is preserved by induction. We are interested here in extensions of this result to moments of order 2 and 3. We have two natural candidates for the second and third … Continue reading Françoise Pène (Université de Bretagne Occidentale, France)
