A strongly regular graph srg(v,k,lambda,mu) is a graph with v vertices that is regular of valency k and that has the following properties: (1) For any two adjacent vertices x,y, there are exactly lambda vertices adjacent to both x and y. (2) For any...

PIMS' L-functions and Number Theory CRG is currently ramping up its activities in preparation for the Focus Period in Number Theory. The first focus period takes place from May 29-July 5, 2011. The premiere event is from May 29-June 3, 2011, when the...

I will continue our treatment, started by Masoud last week, of Deligne's Le formalisme des cycles évanescents (SGA 7, Exposé XIII) by covering topics from Sections 1.3, 1.4 and 2.1.

Topological phases of matter have captured our imagination over the past few years, with tantalizing properties such as robust edge modes and exotic non-Abelian excitations, and potential applications ranging from semiconductor spintronics to...

Abstract: Quillen introduced a notion of homology in terms of derivedabelianization. Working in the contexts of operadic algebras in chain complexes and spectra, we prove a finiteness theorem relating finiteness properties of Quillen homology groups...

Abstract: Diophantine equations, one of the oldest topics of mathematical research, remain the object of intense and fruitful study. A rational solution to a system of algebraic equations is tantamount to a point with rational coordinates (briefly, a...
