"Morphisms of horospherical varieties"

In this talk, we define and look at examples of morphisms of horospherical varieties. Additionally, we will see how morphisms of horospherical varieties are related to maps of the coloured fans.

This seminar will be held jointly online and in person:

"Lower bounds on solubility of Diophantine systems"

Given a system of r homogeneous polynomial equations with degree d with rational coefficients, we study the number of variables it needs to possess a non-trivial p-adic solution. We focus on the lower bound of this number. We learn the history and prototype of the problem, as well as the most precise estimation of the lower bound so far.

"Properties of horospherical varieties"

We study when a given horospherical variety is affine. Additionally, we study G-orbits of horospherical varieties and their correspondence with colored cones.
