Theoretical computer science | Systems of set theory | Approximations
In computer science, a rough set, first described by Polish computer scientist Zdzisław I. Pawlak, is a formal approximation of a crisp set (i.e., conventional set) in terms of a pair of sets which give the lower and the upper approximation of the original set. In the standard version of rough set theory (Pawlak 1991), the lower- and upper-approximation sets are crisp sets, but in other variations, the approximating sets may be fuzzy sets. (Wikipedia).

Peter Friz (TU and WIAS Berlin) -- Laplace method on rough path and model space
Laplace's method allows one to obtain precise asymptotics in the large deviation principle. I will review the case of rough paths, then talk about extensions to rough volatility and singular SPDEs. Joint work with Paul Gassiat (Paris), Paolo Pigato (Rom) and Tom Klose (Berlin).

Felix Otto: Singular SPDE with rough coefficients
Abstract: We are interested in parabolic differential equations (∂t−a∂2x)u=f with a very irregular forcing f and only mildly regular coefficients a. This is motivated by stochastic differential equations, where f is random, and quasilinear equations, where a is a (nonlinear) function of u.
