Lieb-Thirring bounds for Melik-Adamyan canonical Hamiltonians

Baruch Schneider, Diana Barseghyan Schneiderová, Yifan Zhang

We study a class of positive matrix Hamiltonians arising from the canonical differential expressions of Melik--Adamyan and appearing in the appendix of Alpay--Gohberg. Let and…
