Title: New invariants of minimal border rank tensors
Abstract: The border rank of a tensor is a basic measure of its complexity. Yet, very little is known even for small sized tensors. In the talk I will explain the main open problems and recent developments connected to newly introduced 111-algebras which allow to apply commutative algebraic and deformation theoretic results to this problem.
For most part of the talk, this is joint with J.M. Landsberg and A. Pal.
