"Global structure results in algebraic geometry"
It is a classical result that any smooth manifold can be embedded into Euclidean space. However, the analogous statement is false in the algebraic setting. Indeed, there are many varieties which cannot be embedded in Euclidean (or even projective) space!
In this talk we will discuss a way to salvage this deficiency using algebraic vector bundles. Indeed, a result of Totaro explains why the existence of special vector bundles implies a higher-rank analogue of the embeddability results above. We will then explain why the Brauer group, a repository of arithmetic and geometric data, can help achieve new global structure results in this direction.

The University of Waterloo acknowledges that much of our work takes place on the traditional territory of the Neutral, Anishinaabeg and Haudenosaunee peoples. Our main campus is situated on the Haldimand Tract, the land granted to the Six Nations that includes six miles on each side of the Grand River. Our active work toward reconciliation takes place across our campuses through research, learning, teaching, and community building, and is centralized within our Office of Indigenous Relations.
