POSINORMAL TERRACED MATRICES
Rhaly, H. Crawford, Jr.;

Abstract
This paper is a study of some properties of a collection of bounded linear operators resulting from terraced matrices M acting through multiplication on $\small{{\ell}^2}$; the term terraced matrix refers to a lower triangular infinite matrix with constant row segments. Sufficient conditions are found for M to be posinormal, meaning that $MM^* Keywords $\small{Ces{\grave{a}}ro}$ matrix;terraced matrix;dominant operator;hyponormal operator;posinormal operator; Language English Cited by 1.
