ON RANK ONE PERTURBATIONS OF THE UNILATERAL SHIFT
Ko, Eung-Il; Lee, Ji-Eun;

Abstract
In this paper we study some properties of rank one perturbations of the unilateral shift operators $\small{T=S+u{\otimes}{\upsilon}}$. In particular, we give some criteria for eigenvalues of T. Also we characterize some conditions for T to be hyponormal.
