G. Szego showed that inf/ \l-f\2wd6/2n = exp( XogwdO/ln Jo Jo where / ranges over analytic polynomials with mean value zeros. We study extensions of the Szego's theorem on the disc to the bidisc We show that the quantity is a mixed form of an arithmetic mean and a geometric one of w in some special cases.
