The polynomial cluster value problem

Functional Analysis 2018-01-30 v3

Abstract

The polynomial cluster value problem replaces the role of the continuous linear functionals in the original cluster value problem for the continuous polynomials to describe the corresponding cluster sets and fibers. We prove several polynomial cluster value theorems for uniform algebras H(B)H(B) between Au(B)A_u(B) and H(B)H^{\infty}(B), where BB is the open unit ball of a complex Banach space XX. We also obtain new results about the original cluster value problem, especially for A(B)A_{\infty}(B). Examples of spaces XX considered here are spaces of continuous functions, 1\ell_1 and locally uniformly convex spaces.
