“Borel subgroups of Aut(A^n)”<\/p>\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 $X=\\mathbb{A}^n$.<\/p>\n
This is joint work with Andriy Regeta and Daniel Daigle.<\/p>\n
