We first show that the canonical solution operator to <(<partial derivative
>)over bar> restricted to (0,1)-forms with holomorphic coefficients can be
expressed by an integral operator using the Bergman kernel. This result is
used to prove that in the case of the unit disc in C the canonical solution
operator to <(<partial derivative>)over bar> restricted to (0; 1)-forms wi
th holomorphic coefficients is a Hilbert-Schmidt operator. In the sequel we
give a direct proof of the last statement using orthonormal bases and show
that in the case of the polydisc and the unit ball in (Cn), n>1; the corre
sponding operator fails to be a Hilbert-Schmidt operator. We also indicate
a connection with the theory of Hankel operators.
