摘要

This addendum to [1] completely characterizes the boundedness and compactness of a recently introduced integral type operator from the space of bounded holomorphic functions H-infinity(D-n) on the unit polydisk D-n to the mixed norm space A(alpha)(p,q) (D-n) with p, q is an element of [1, infinity) and alpha = (alpha(1), ..., alpha(n)) such that alpha(j) > -1 for every j = 1, ..., n. We show that the operator is bounded if and only if it is compact g is an element of A(alpha+(q) over right arrow)(p,q)(D-n), where (q) over right arrow = (q, ..., q).
