Abstract

In 1984, Andrews introduced the family of partition functions cϕk(n)c\phi_k(n), which counts the number of generalized Frobenius partitions of nn with kk colors. In previous work, we proved a conjecture on congruences for cϕ6(n)c\phi_6(n) modulo powers of 3. In this paper, we consider the (6,0)(6,0)-colored Frobenius partition functions cψ6,0(n)c\psi_{6,0}(n). We establish a connection between the generating functions of cψ6,3(n)c\psi_{6,3}(n) and cψ6,0(n)c\psi_{6,0}(n) via an Atkin-Lehner involution, and prove congruences modulo powers of 3 for cψ6,0(n)c\psi_{6,0}(n).
