Title: On the geometry of geometric rank

Abstract: Geometric Rank of tensors was introduced by Kopparty et al. as a useful tool to study algebraic complexity theory, extremal combinatorics and quantum information theory. In this talk I will introduce Geometric Rank and results from their paper, in particular showing the relation between geometric rank and other ranks of tensors. Then I will present recent results based on joint work with J.M. Landsberg, including classification of tensors with geometric rank two.
