• 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.
