"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:
