报告摘要：

     Recently, George Beck introduced two partition statistics NT(m,j,n) and M_ω (m,j,n), which denote the total number of parts in the partition of n with rank congruent to m modulo j and the total number of ones in the partition of n with crank congruent to m modulo j, respectively. Andrews proved a congruence on NT(m,5,n), which was conjectured by Beck. Very recently, Chan, Mao and Osburn established a number of Andrews-Beck type congruences and posed several conjectures involving NT(m,j,n) and M_ω (m,j,n). Some of those conjectures were proved by Chern and Mao. In this paper, we confirm the remaining three conjectures of Chan-Mao-Osburn and three conjectures due to Mao. We also present two new conjectures on NT(m,j,n) and M_ω (m,j,n). This work was jointed with Jin, Liu and Mao.
