Speaker: JM Landsberg, Texas A&M

Title: The cheapest tensors

Abstract: Motivated by quantum information theory and the complexity of matrix multiplication, one would like to classify tensors of "minimal border rank". This is now understood to be a difficult problem with deep connections to algebraic geometry and commutative algebra. After giving an introduction to the topic with motivation and basic definitions, I will describe recent progress on the question, in particular the introduction of "atomic tensors". This is joint work in progress with J. Jelisiejew and T. Mandziuk.
