Letbe a measure on the polydiscwhich is the product ofnregular Borel probability measures so thatfor all 0 <r< 1. The Bergman spaceconsists of all holomorphic functions that are square integrable with respect to. In one dimension, it is well known that iffis continuous on the closed disc, then the Hankel operatorHfis compact on. In this paper we show that forn≥ 2 andfa continuous function on,Hfis compact onif and only if there is a decompositionf=h+g, wherehbelongs toand.
