Abstract
In the BMN approach to 
= 4 SYM a large class of
correlators of interest are expressible in terms of expectation values
of traces of words in a zero-dimensional gaussian complex matrix
model. We develop a loop-equation based, analytic strategy for
evaluating such expectation values to any order in the genus
expansion. We reproduce the expectation values which were needed for
the calculation of the one-loop, genus one correction to the anomalous
dimension of BMN-operators and which were earlier obtained by
combinatorial means. Furthermore, we present the expectation values
needed for the calculation of the one-loop, genus two correction.
