Positive Planar Measures for Spectral Pinching and the Corrected BMV Conjecture

Trung Hoa Dinh, Cong Trinh Le, Trung Dung Vuong

We prove the corrected Bessis--Moussa--Villani pinching conjecture for all symmetrized word averages. For Hermitian matrices $A, B$ and $D = E_{A} (B)$ , we construct a positive compactly…

A Weighted Spectral Quantum Fidelity

Cong Trinh Le, The Khoi Vu, Minh Toan Ho +1

We introduce and study a one-parameter family of fidelity-type quantities based on the weighted spectral geometric mean, which we call the \emph{weighted spectral fidelity} \( \mat…
