ABSTRACT
We can use our previous work on single integral operators on each of these
integrals. If we apply (4.2-4) with n = y = 1 to f, we obtain Re G(z) > 0, when Ill I ::::; 1. If we then apply ( 4.2-5) and ( 4.2-6) to G we obtain Re F(z) > 0. This two step operation yields the same result as (4.2-13), but
