"Divisors and line bundles, Part II"
This week, we finish the discussion we started last week on the relationship between divisors and line bundles on complex varieties. We also describe the divisor class groups and the Picard groups of toric varieties.
The seminar will meet on Zoom:

"Representation of General Linear Group over Finite Field"
This talk aims at discussing the techniques used in finding all the irreducible representations of general linear groups over finite fields. A brief overview of representation theory is also provided, but no such overview is provided for group theory and field theory.

"Divisors and line bundles, Part III"
In this week's talk, we finally describe the relationship between divisors and line bundles on complex varieties, illustrating it with some explicit examples.

"Divisors on toric varieties"
I will continue from the last few talks on divisors by highlighting some important features of the toric case. The focus will be on torus invariant divisors and tools for computing the class group and Picard group of toric varieties.

"Subalgebras of so(7) Induced by the Coassociative 4Form on R^7"
Consider the 2forms on R^7 resulting from evaluating the coassociative 4form on two vectors. It turns out that, when such vectors are restricted to an associative 3plane P, these 2forms along with those in Λ^2(P) give a subalgebra of so(7) isomorphic to so(3) ♁ so(3). After giving some brief context, we will discuss this fact and characterize the intersections of such subalgebras for different choices of P.

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 Indigenous Initiatives Office.
