Quantification of Blow-up Levels for a 2-D Elliptic Equation with Critical Exponential Nonlinearity

We study sequences of solutions of some elliptic PDE’s, on 2-dimensional bounded domain, with critical Moser-Trudinger exponential nonlinearity. We prove that lack of compactness occur only when standard bubbles appear and thus we can quantify t   more››

Large Inverse Problems and Infinite Dimensional Sampling: Stochastic PDE for Sampling Conditioned SD

There are a variety of important applications which may be formulated as inverse problems where the object of interest is the time-dependent solution of a dynamical system. Examples include the sampling of rare events in molecular dynamics, data assi   more››

Quantum Information Theory for Mathematicians

In this talk I will give an overview of quantum information theory, with an emphasis on some of the underlying mathematics. In particular, quantum algorithms depend on a physical property of quantum systems,entanglement, which may be characterized   more››

Rolling is an important manifestation of biological cell adhesion, especially for the leukocyte cell in the immune process. It combines several phenomena such as the affinity, the junction and failure between specific adhesion molecules, and an ac   more››

We study the concepts of homotopy disjointness and homotopy disjointness by small deformation for mappings between spheres. Joint work with Daciberg Goncalves produced the following result. The existence of a mapping f: S^(4n-2)   more››

The first part of the talk gives a survey about BSDE. Linear BSDE have been introduced by Bismuth (1973) in Control Theory. The existence of solutions for Lipschitz BSDE was proven by Peng, and for quadratic BSDE by Lepeltier/San Martin and by Kob   more››

Renormalization analysis of hierarchically interacting two-type branching models

Linearly interacting diffusions model the evolution of colonies of populations. When the interaction kernel is of an appropriate form and the diffusions are indexed by the hierarchical group, the large scale space-time behavior of the system exhib   more››

Wavelet techniques for processing multifractal signals

Multifractal analysis has been successfully applied to many types of signals, starting from turbulence velocity fields, and then extending to traffic, economic and medecine signals. In each case, it supplies new parameters which allow for a fine c   more››

Bootstrap Percolation in d Dimensions

Modified bootstrap percolation is a very simple cellular automaton model for nucleation and growth. Sites in the cube {1,...,L}^d are initially occupied independently with probability p. At subsequent steps, an unoccupied site becomes occupied if   more››

Polarisation and cell movement: a multiscale modelling approach

Cell motility is a complex phenomenon, in which the cytoskeleton and its major constituent, actin, play an essential role. To understand the intricated interplay which brings about cell motility, we use a multiscale modelling approach in a 2D model o   more››

Channel Assignments in Infinite Graph

We study quaternionic (especially hyperkahler) analogues of Lerman's symplectic cut construction. In low dimensions this can be physically interpreted as adding a brane to a hyperkahler manifold   more››
