Constructive Invariant Theory
Harm Derksen (Univ. of Michigan)
Location: Hill 705
Date & time: Friday, 12 October 2018 at 4:00PM - 5:00PM
Abstract: If a group G acts on a vector space V by linear transformations, then the invariant polynomial functions on V form a ring. In this talk I will give an overview of known upper and lower bounds for the degrees of generators of this invariant ring. This includes recent results by Visu Makam and the speaker on some cases where polynomial upper bounds exists, and some cases where we have exponential lower bounds.
