TITLE: Extending Kantorovich-Type Inequalities to Normal Operators
AUTHORS: Morteza Seddighin
KEYWORDS: Kantorovich-Type Inequalities
JOURNAL NAME: Advances in Linear Algebra & Matrix Theory, Vol.8 No.1, March 12, 2018
ABSTRACT: We will extend some of the Kantorovich-Type inequalities for positive finite dimensional matrices to infinite dimensional normal operators by applying The Two-Nonzero Component Lemma and converting them to an An-tieigenvalue-Type problem.
