MATH Seminar: “Borel subgroups of Aut(A^n)”, Michael Chitayat, 3:40PM April 10 2026 (EN)

You are cordially invited to the ODTU-Bilkent Algebraic Geometry Seminar.

Speaker: Michael Chitayat (University of Padova)

“Borel subgroups of Aut(A^n)”

Abstract: Let $X$ be an affine variety. It was recently proved that a connected solvable $G\subseteq \rm{Aut}(X)$ can be decomposed as a semi-direct product $G=T\ltimes U$ where $T$ is an algebraic torus and $U$ is a nested unipotent subgroup. A $\textit{Borel Subgroup of}$ $\rm{Aut}(X)$ is a maximal element of the set of connected solvable subgroups of $\rm{Aut}(X)$. In this talk I will discuss Borel subgroups of $\rm{Aut}(X)$ with a focus on the special case where $X=\mathbb{A}^n$.

This is joint work with Andriy Regeta and Daniel Daigle.
