Speaker

Prof. Shmuel Friedland (University of Illinois Chicago)

Description

In this talk we survey some recent results on entanglement and separability of general, symmetric (bosons), skew-symmetric (fermions) tensors, and their computability. All these results are related to corresponding numerical radii. This talk is based on the arXiv preprint

S. Friedland, Tensors, entanglement, separability, and their complexity, arXiv:2509.21639, 2025.
