Title: A Brief Introduction to Rough Paths
Abstract: Rough Paths are a suitable generalization of smooth paths in settings where classical (Riemann-Stieltjes, Young, ...) integration breaks down, most notably for integral formulations of (stochastic/controlled) differential equations. We'll give a short account of the key objects, spaces, properties involved, as well as some subtleties of the theory. The focus of the talk is going to be on the motivation via the "Rough Path principle" and rough integration as well as on "the big picture".

Title: The chemical distance in random interlacements in the low-intensity regime
Abstract: Random interlacements is a Poissonian soup of doubly-infinite random walk trajectories on Z^d, with a parameter u > 0 controlling the intensity of the Poisson point process. In a natural way, the model defines a percolation on the edges of Z^d with long-range correlations. We consider the time constant associated to the chemical distance in random interlacements at low intensity u > 0. It is conjectured that the time constant times u^{1/2} converges to the Euclidean norm, as u ↓ 0. In dimensions d ≥ 5, we prove a sharp upper bound and an almost sharp lower bound for the time constant as the intensity decays to zero. Joint work with Eviatar Procaccia and Ron Rosenthal.
