I will discuss the following question independently posed by Clark and Saltman around 2007: Given a central simple algebra A over a field K, is there a a genus 1 curve X over K such that A is split by the function field K(X)? Federico Scavia and I...

The Cremona dimension of a finite group G is the minimal dimension of a rationally connected variety which admits a faithful action of G. In this talk, based on joint work with Giulio Bresciani and Angelo Vistoli, I will discuss new lower bounds on...

WAGS aims to build a regional community among algebraic geometers of all career stages, from advanced undergraduates to full professors. The meetings are centered around research talks delivered by leading mathematicians from around the world...

The "ABC algebra workshops" is a series of PIMS-sponsored research workshops on algebra and related topics. Originally designed to bring together researchers from the Universities of Alberta and British Columbia (thus the acronym ABC), these...

The term “versal” is best understood by subtracting “unique” from both sides of the formulaUniversal = unique + versal.In this talk based on joint work with Alex Duncan, I will discuss competing notions of versality for the action of an algebraic...

Let k be a field, A be a finite-dimensional k-algebra (not necessarily commutative, associative or unital), and R be a commutative ring containing k. An R-algebra B is called an R-form of A if there exists a faithfully flat ring extension S/R such...
