Congruences modulo powers of $5$ for odd ranks

Combinatorics 2024-08-20 v1

Abstract

In 2007, Andrews studied the odd Durfee symbols and their odd ranks. Let N0(m,k,n)N^0(m,k,n) denote the number of odd Durfee symbols of nn with odd rank congruent to mm modulo kk. Motivated by Andrews' work, many authors obtained generating functions of N0(m,k,n)N^0(m,k,n) from which relations between odd ranks are proved. In this paper, we establish a family of congruences for odd ranks modulo powers of 55.
