The 57th Cascade Topology Seminar will take place at Seattle University. The titles and abstracts for this event are: Ryan Derby-Talbot: Computing Heegaard genus is NP-Hard One of the most basic measures of the complexity of a 3-manifold is its...

Northwest Probability Seminars are mini-conferences held at the University of Washington and organized in collaboration with the Oregon State University, the University of British Columbia and the University of Oregon. There is no registration fee...

I will discuss recent new developments in De Giorgi Conjecture for Allen-Cahn equation. In dimensions up to 10, we shall establish the C2,α estimates of level sets for stable solutions of Allen-Cahn. By applying reverse gluing method we show that the...

Many results in extremal graph theory can be formulated as inequalities on graph densities. While many inequalities are known,many more are conjectured. A standard tool to establish an inequality is to write the expression whose nonnegativity needs...

In number theory and diophantine geometry, the theory of "heights" is essential in studying finiteness questions. Roughly, they capture the "arithmetic complexity" of the object of study. We give a formula relating various notions of heights of...

Algebraic geometry is the study of geometric objects defined as the solution set of a system of polynomial equations p1,…,pr∈F[x1,…,xn] where F is an algebraically closed field. After recent spectacular progress in the classification of varieties...

A connection is a geometric object that allows to parallel transport vectors along a curve in a domain. A natural question that often arises is whether one can recover a connection inside a domain from the knowledge of the parallel transport along a...

In his 1983 research announcement “Some results in harmonic analysis in R^n, for n → ∞” (Bulletin of the AMS), E.M. Stein announced new results for several classical operators in harmonic analysis with operator norms that do not depend on the...

In recent years the field of complex analysis has evolved into various new areas, including random conformal maps, dynamical systems, geometric function theory broadly construed, and it has even seen applications to discrete networks. While all of...

The Pacific Northwest Geometry Seminar (PNGS) is a regional meeting for geometers of all kinds. It is held once each academic year, rotating among Seattle, WA, Portland, OR, and Vancouver, BC. It is sponsored by Lewis and Clark College, Oregon State...
