Optimal matching problems are random variational problems widely investigated in the mathematics and physics literature. We discuss here the optimal matching problem of an empirical measure on a sample of iid random variables to the…
Consider the fractional Brownian motions on the real line. What should we expect if we replace the real line by a manifold M? We will provide an answer to this question, extending work begun by…
In joint work with Soumik Pal, we study natural mixing processes where cards (or dominoes or mahjong tiles) are ‘smushed’ around on a table with two hands. How long should mixing continue. If things are…
Given n uniform points on the surface of a two-dimensional sphere, how can we partition the sphere fairly among them? “Fairly” means that each region has the same area. It turns out that if the…
Modern data often consists of feature vectors with a large number of features. High-dimensional geometry and Linear Algebra (Singular Value Decomposition) are two of the crucial areas which form the mathematical foundations of Data Science.…

Microsoft is a silver sponsor of LISA17, the annual vendor-neutral meeting place for the wider system administration community. The program will address the overlap and differences between traditional and modern IT operations and engineering, curated…
