Transport of nonlinear oscillations along rays that graze a convex obstacle to any order Abstract. When a wave interacts with a convex obstacle, it creates reflected waves, as well as waves in the geometric shadow of the obstacle. This phenomenon … Read more
Positive geometry Abstract. Positive geometries are topological spaces sitting inside algebraic varieties that generalize convex polytopes embedded in projective space. Examples of positive geometries appear in the study of total positivity, toric varieties, and configuration spaces. I will give a … Read more
Title: Monotone links in the DAHA and EHA Abstract: Morton and Samuelson related certain skein algebras on the torus with the double affine Hecke algebra (DAHA) and the elliptic Hall algebra (EHA). We use this construction to study link homology … Read more

Long range wave dependencies and cosine sign correlations Abstract. We’ll introduce and discuss a very strange phenomenon which, approximately, says that quantum particles on nice manifolds can exhibit some very strange form of non-locality and can communicate across very large … Read more

A problem for a material surface attached to the boundary of an elastic semi-plane Abstract. A problem for a nano-sized material surface attached to the boundary of an elastic isotropic semi-plane is considered. A normal external traction is applied to … Read more

Coarsening dynamics of condensing fluid thin films Abstract: The behavior of thin layers of viscous fluids coating solid surfaces is of importance in many industrial and natural applications. Interfacial instabilities and pattern formation can occur in films on water-repellent surfaces. Thin … Read more
