Abstract

Let V be a bounded pseudoconvex Reinhardt domain in C^2 with many strictly pseudoconvex points and logarithmic image W. It was known that the maximal ideal in H(V)H^{\infty}(V) consisting of all functions vanishing at (p,q) in V is generated by the coordinate functions z-p, w-q (meaning that one can solve the Gleason problem for H(V)H^{\infty}(V)) if W is bounded. We show that one can solve Gleason's problem for H(V)H^{\infty}(V) as well if there are positive numbers aa, bb and a positive rational number k/l such that V looks like {(z,w) in C^2 : a |w|^l <= |z|^k = b |w|^l} for small (z,w).
