Compressive sensing (CS) is a general paradigm that enables us to measure objects (such as images, signals, or functions) by using a number of linear measurements proportional to their sparsity, i.e. to the minimal amount of information needed to...

In early 90's, there are two mathematical theories motivated by physics, Verlinde theory counting the number of generalized theta function on a curve and quantum cohomology counting the number of holomorphic maps. Early explicit computation shows...

Cambridge declared its first Senior Wrangler in 1748 (John Bates), the student who finished highest in the 3rd year undergraduate, so-called Mathematical Tripos Exams. The Maths Tripos Exams run approximately for 60 hours over a period of 10 days...

The “cap set” problem asks the following question. Let S be a subset of an n-dimensional vector space over F_3 such that no three distinct elements of S are collinear. How big can S be? This is related to classical number theory questions about sets...

In '99, David Aldous conjectured that a certain natural "random walk" on the space of binary combinatorial trees should have a continuum analogue, which would be a diffusion on the Gromov-Hausdorff space of continuum trees. This talk discusses...

The Min system in E. coli is one of the simplest known biological systems that demonstrates diverse complex dynamic behavior or transduces local interactions into a global signal. Various mathematical models of the Min system show behaviors that are...

To a 3-manifold with torus boundary, we can associate an element of the Fukaya category of the punctured torus—that is, a collection of immersed curves in the torus, decorated with local systems—such that when two such manifolds are glued the...

There is growing concern about fairness in algorithmic decision making: Is it treating different groups fairly? How can we make it fairer? And what do we even mean by fair? In this talk I will discuss some of our work on this topic, focusing on the...

Suppose G is a finite group of order 6pq such that p and q are distinct prime numbers. It is conjectured that, if S is any generating set of G, then there is a Hamiltonian cycle in Cay(G;S). The talk will discuss a special case of this problem which...
