Hankel Operators Defined Between K\"othe Spaces

Abstract

This paper is about the operators defined between K\"othe spaces whose associated matrix is a Hankel matrix. After demonstrating how these operators are defined, the conditions for continuity and compactness of these operators are constructed. It is shown that the backward and forward shift operators are mean ergodic and Ces\`aro bounded by establishing a relationship between the backward and forward shift operators and Hankel and Toeplitz operators on power series spaces.
