Abstract

In this paper, we give an easy description of the elementary divisors of the Cartan matrices for symmetric groups in terms of the lengths of p -regular partitions and their Glaisher correspondents. Moreover, for p = 2 , it is done block wise. There we use certain kinds of cores and weights, which are similar to but different from the usual ones.
