Abstract Results on the effective equidistribution of closed, cuspidal horocycles were first proved by Zagier (1981) and Sarnak (1981). The results were later extended to all finite areasurfaces and arbitrary orbits (Burger, … 30 May 2017 16:30 - 17:30 Event Arnaud Chéritat Generic Perturbation of Parabolic Points Having More Than One Attracting Petal Symposium Dynamic systems conference. Abstract With Christiane Rousseau we study generic one-parameter perturbation of holomorphic vector fields in complex dimension one, with the aim of applying this to the study of bifurcation loci of one-parameter … 30 May 2017 15:30 - 16:30 Series Brain longevity (continued) Alain Prochiantz, chair Morphogenetic processes Lecture Every day, cells are subjected to several hundred thousand lesions affecting proteins, lipids and DNA. In the nervous system alone, there are around 200 cytosine deaminations, 3,000 guanine methylations, 10,000 spontaneous depurations, up to 100,000 … 06 Oct 2014 → 17 Nov 2014 Event Enrique Pujals Strong Dissipative Diffeomorphisms of the Disk with Zero Entropy: Structure of Periodic Points and infinite Renormalization Symposium Dynamic systems conference. Abstract We will discuss a class of volume-contracting surface dieomorphisms (named strong dissipative dieomorphisms) whose dynamics is intermediate between one-dimensional dynamics and general surface dynamics. For the … 30 May 2017 14:00 - 15:00 Event Vadim Kaloshin Birkhoff Conjecture for Convex Planar Billiards and Deformational Spectral Rigidity of Planar Domains Symposium Dynamic systems conference. Abstract The classical Birkhoff conjecture states that the only integrable convex planar domains are circles and ellipses. We show that this conjecture is true for perturbations of ellipses. It turns out that the method of … 30 May 2017 11:00 - 12:00 Event Etienne Ghys Singularities of Real Analytic Curves Symposium Dynamic systems conference. … 30 May 2017 09:30 - 10:30 Event Corinna Ulcigrai On Birkhoff Sums and Roth Type Conditions for Interval Exchange Transformations Symposium Dynamic systems conference. Abstract Understanding growth and behaviour of Birkhoff sums is one of the central themes in the study of interval exchange transformations (IET), starting from the work of Zorich and Forni on deviations of ergodic averages, up … 29 May 2017 15:30 - 16:30 Event Marcelo Viana Lyapunov Exponents of Continuous Cocycles Symposium Dynamic systems conference. Abstract The Mañé-Bochi theorems that the Lyapunov exponents of continuous SL(2)-cocycles over any invertible aperiodic system may always be anihilated by arbitrarily small perturbations, unless the cocycle is uniformly … 29 May 2017 16:30 - 17:30 Event Curtis Mc Mullen Plane Cubics, Quadrilaterals and Totally Geodesic Surfaces in Moduli Space Symposium Dynamic systems conference. Abstract We will describe new examples of totally geodesic curves and surfaces in the moduli spaces Mg ;n . These examples connect Teichmueller theory to classical projective geometry, and emerge from the study of billiards in … 29 May 2017 14:00 - 15:00 Event Mikhail Lyubich Pacman Renormalization and Scaling of Satellite Mandelbrot Copies near Siegel Points Symposium Dynamic systems conference. Abstract In the 1980s Branner and Douady discovered a surgery relating various limbs of the Mandelbrot set. We put this surgery in the framework of "Pacman Renormalization Theory" that combines features of quadratic-like and … 29 May 2017 11:30 - 12:30 Event Hakan Eliasson Almost Reducibility for the Quasi-Periodic Linear Wave Equation Symposium Dynamic systems conference. Abstract The linear wave equation on a torus with a mass term and perturbed by a potential depending quasi-periodically on time becomes, when written in Fourier coefficients, an infinite dimensional symplectic quasi-periodic … 29 May 2017 10:00 - 11:00 Event Alexandre Pouget I doubt therefore I am : the probabilistic brain Seminar 29 May 2017 17:00 - 18:30 Event Alain de Libera Questions Symposium 30 May 2017 17:40 - 18:00 Event Irene Caiazzo The laity and philosophy in the twelfth century : a long history Symposium 30 May 2017 17:00 - 17:40 Event Angela B.
