Abstract:
It is proved that if the increasing sequence {kn} n=0..∞
n=0 of nonnegative integers has density greater than 1/2 and D is an arbitrary simply
connected subregion of C\R then the system of Hermite associated functions
Gkn(z) n=0..∞ is complete in the space H(D) of complex functions holomorphic in D.
