There will be some short presentations followed by a discussion with our panel of experts. You will learn the secrets of writing an effective research statement, developing an outstanding CV, and giving a winning job talk. We will address questions...

A finite family of (straight) lines in the projective plane is a simplicial arrangement provided all faces (connected components of the complement) are triangles (simplices). Similarly for arrangements of (hyper) planes in higher dimensions. Starting...

In the local Langlands program the (smooth) representation theory of p-adic reductive groups G in characteristic zero plays a key role. For any compact open subgroup K of G there is a so called Hecke algebra H(G,K). The representation theory of G is...

This year marks the 100th anniversary of the birth of the "father of computer science," Alan Turing. His legacy is recognized with the Turing Award, the "Nobel prize" of computer science. The Department of Computer Science is honoured to host 2010...

Abstract: The study of quadratic forms is a classical and important topic of algebra and number theory. A natural example is the trace form of a finite Galois extension. This form has the additional property of being invariant under the Galois group...

Abstract:The Sylvester-Gallai Theorem states that, given any set P of n points in the plane not all on one line, there is at least one line through precisely two points of P. Such a line is called an ordinary line. How many ordinary lines must there...

We study the regularity of solutions of parabolic equations of the form u_t - Iu = f, where I is a fully non linear non local operator. We prove C^\alpha regularity in space and time and, under different assumptions on the kernels, C^{1,\alpha}; in...

Doodling has many mathematical aspects: patterns, shapes, numbers,and more. Not surprisingly, there is often some sophisticated and funmathematics buried inside common doodles.I’ll begin by doodling, and see where it takes us.It looks like play, but...

Since the famous work of V. Scheffer about 20 years ago, it has been known that the Cauchy problem for the incompressible Euler equations has non-unique weak solutions. Recently, De Lellis and Szekelyhidi demonstrated that this phenomenon can be...
