We will describe a current approach to understanding stationary states in non-equilibrium statistical mechanics. We will then consider two examples: a system of stochastic differential equations for coupled oscillators, and a stochastic wave equation...

In the 1960s, Wall developed a theory of finiteness obstructions for CW-complexes. We extend this result to diagrams of spaces and use it to investigate which homotopy G-spheres can be realized on a finite complex. We will conclude with some new...

We present a general variational method, involving self-dual variational calculus, for recovering non-linearities from prescribed solutions for certain types of PDEs which are not necessarily of Euler-Lagrange type, including parabolic equations. The...

Computer algebra systems like Maple and Mathematica spend most of their time doing either polynomial arithmetic or linear algebra. For polynomials in one variable of degree n, the Fast Fourier Transform gives us an O(n log n) multiplication algorithm...

In symbolic dynamics, a Z^d shift of finite type (or SFT) is the set of all ways to assign elements from a finite alphabet A to all sites of Z^d, subject to local rules about which elements of A are allowed to appear next to each other. A fundamental...

I will discuss some deformation properties of Fano varieties. The general methods rely on the investigation of the variation of the cone of effective curves and, more generally, of the Mori chamber decomposition, which, according to Mori theory...

The West Coast Optimization Meeting has a long tradition as a regional meeting bringing together mathematicians working in optimization and related areas. It traditionally meets twice a year, once at the University of Washington, and once at UBC or...

Northwest Probability Seminars are one-day mini-conferences held at the University of Washington and organized in collaboration with the Oregon State University, the University of British Columbia, the University of Oregon, and the Theory Group at...

When several large integers are added in the usual way 'carries' occur along the way. It is natural to ask: 'About how many carries are there and how are they distributed for typical numbers?' It turns out that these questions are intimately related...
