Symmetric and Antisymmetric Tensor Products for the Function-Theoretic Operator Theorist

Stephan Ramon Garcia, Ryan O'Loughlin, Jiahui Yu

We study symmetric and antisymmetric tensor products of Hilbert-space operators, focusing on norms and spectra for some well-known classes favored by function-theoretic operator th…

Crouzeix's conjecture for classes of matrices

Ryan O'Loughlin, Jani Virtanen

For a matrix which satisfies Crouzeix's conjecture, we construct several classes of matrices from for which the conjecture will also hold. We discover a new link between cy…
