Abstract

Let E be a Banach space, with unit ball BE. We study the spectrum and the essential spectrum of a composition operator on H(BE) determined by an analytic symbol with a fixed point in BE. We relate the spectrum of the composition operator to that of the derivative of the symbol at the fixed point. We extend a theorem of Zheng to the context of analytic symbols on the open unit ball of a Hilbert space.
