Abstract Operator Systems and Spectrahedra

Slides - Abstract Operator Systems over the Cone of Positive Semidefinite Matrices

In 2022 I gave a talk about our paper Abstract Operator Systems over the Cone of Positive Semidefinite Matrices.

I discussed the definitions of abstract operator systems and their concrete realization and the notion of free spectrahedra, how they relate too each other and which admit a representation as a free spectrahedron.
