Title:  Non-commutative Rank, Quivers, and Tensors

Abstract:   Fortin and Reutenauer defined the non-commutative rank for a matrix with entries
that are linear functions. We will generalize this non-commutative rank to both the representation theory of quivers, and to tensor spaces. In particular, we will relate non-commutative rank to King’s criterion for sigma-stability of quiver representations, general Hom and Ext spaces studied by Schofield, and several notions of tensor rank.

Alana's advisor is Harm Derksen.
