Abstract

Our results concern growth estimates for vector-valued functions of L-index in joint variables whichare analytic in the unit ball. There are deduced analogs of known growth estimates obtained early for functions analytic in the unit ball. Our estimates contain logarithm of sup-norm instead of logarithm modulus of the function. Theydescribe the behavior of logarithm of norm of analytic vector-valued function on a skeleton in a bidisc by behavior ofthe function L. These estimates are sharp in a general case. The presented results are based on bidisc exhaustion of aunit ball.
