Abstract
Recently, Chern proved a number of congruences modulo 5, 7, 11, and 13 on Beck’s partition statistics NT(r, m, n) and \(M_{\omega }(r,m,n)\), which enumerate the total number of parts in the partitions of n with rank congruent to r modulo m and the total number of ones in the partitions of n with crank congruent to r modulo m, respectively. In this paper, we prove some identities on NT(r, 5, n) and \(M_{\omega }(r,5,n)\) which are analogous to Ramanujan’s “most beautiful identity.” These identities along with some identities proved by Mao, and Jin, Liu, and Xia imply all congruences modulo 5 on NT(r, 5, n) and \(M_{\omega }(r,5,n)\) discovered by Chern.
