内容介绍：In his 1984 AMS Memoir, Andrews introduced the family of functions $c\phi_k(n)$, the number of k-colored generalized Frobenius partitions of n. In 2019, Chan, Wang and Yang systematically studied the arithmetic properties of $\textrm{C}\Phi_k(q)$ for $2\leq k\leq17$ by utilizing the theory of modular forms, where $\textrm{C}\Phi_k(q)$ denotes the generating function of $c\phi_k(n)$. In this talk, we first establish another expression of $\textrm{C}\Phi_{12}(q)$, then prove some congruences modulo small powers of 3 for $c\phi_{12}(n)$ by using some parameterized identities of theta functions due to A. Alaca, S. Alaca and Williams. Finally, we also conjecture three families of congruences modulo powers of 3 satisfied by $c\phi_{12}(n)$.
