Abstract
A linked cluster expansion is obtained for the logarithm of the partition function which constitutes an asymptotic expansion in 1/N for a normal system. The result is obtained by means of a new and rather general way of asymptotically evaluating a type of integral common in statistical mechanics.Keywords
