"Interesting results in equidistribution theory"
An infinite sequence is equidistributed in an interval if the "proportion" of its points lying in any given sub-interval corresponds roughly to the length of the sub-interval. In a sense, this can be regarded as an "almost randomness" property, and sometimes shows up naturally in analytic number theory.

"Divisors and line bundles on horospherical varieties"
Using the presentation of horospherical varieties as coloured fans, I will present how to describe Borel-invariant Weil and Cartier divisors combinatorically. Then I will give a description of the Picard group of horospherical varieties and detect geometric properties of them.
This seminar will be held jointly online and in person:

"Hyperbolic Monopoles with Continuous Symmetries"
We examine hyperbolic monopoles with continuous symmetries and develop a structure theorem which generates spherically symmetric hyperbolic monopoles. To do this, we modify the steps laid out in a collaborative paper of mine wherein we proved a similar structure theorem for Euclidean monopoles. We discuss how these steps may be applied to other gauge theoretic objects.
