Abstract

We study the properties of the Volterra and Cesàro operators viewed on the L1-Müntz space MΛ1 with range in the space of continuous functions. These operators are neither compact nor weakly compact. We estimate how far from being (weakly) compact they are by computing their (generalized) essential norm. It turns out that this latter does not depend on Λ and is equal to 1/2.
