Harnack and Shmul'yan pre-order relations for Hilbert space contractions
Catalin Badea, Laurian Suciu
We study the behavior of some classes of Hilbert space contractions with respect to Harnack and Shmul'yan pre-orders and the corresponding equivalence relations. We give some condi…

Classes of contractions and Harnack domination
Catalin Badea, Laurian Suciu, Dan Timotin
Several properties of the Harnack domination of linear operators acting on Hilbert space with norm less or equal than one are studied. Thus, the maximal elements for this relation…
