A pre-order and an equivalence relation on Schur class functions and their invariance under linear fractional transformations
(Theta Foundation, 2014)Motivated by work of Yu.L. Shmul’yan a pre-order and an equivalence relation on the set of operator-valued Schur class functions are introduced and the behavior of Redheffer linear fractional transformations (LFTs) ... -
A pre-order on operators with positive real part and its invariance under linear fractional transformations
(Elsevier, 2014)A pre-order and equivalence relation on the class of Hilbert space operators with positive real part are introduced, in correspondence with similar relations for contraction operators defined by Yu.L. Shmul'yan in [6]. It ...
