Continuity and equivariant dimension
Alexandru Chirvasitu, Benjamin Passer
We study the local-triviality dimensions of actions on -algebras, which are invariants developed for noncommutative Borsuk-Ulam theory. While finiteness of the local-trivialit…

Matrix convex sets over the Euclidean ball and polar duals of real free spectrahedra
Eric Evert, Benjamin Passer
We show that the free spectrahedron determined by universal anticommuting self-adjoint unitaries is not equal to the minimal matrix convex set over the ball in dimension three or h…

Extreme points of matrix convex sets and their spanning properties
Eric Evert, Benjamin Passer, Tea Å trekelj
This expository article gives a survey of matrix convex sets, a natural generalization of convex sets to the noncommutative (dimension-free) setting, with a focus on their extreme…
