报告1Proofs of some conjectures of Chan-Mao-Osburn onBeck's partition statistics,夏先伟 苏州科技大学教授;

报告摘要:Recently, George Beck introduce two partition statistics NT(m,j,n) and M_{\omega}(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_{\omega}(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-Osburnand three conjecture due to Mao. We also present two new conjectures on M_{\omega}(m,j,n) and NT(m,j,n). This work was jointed with Jin, Liu and Mao.

报告2New proofs of some double sum Rogers-Ramanujan type identities,王六权,武汉大学副教授。

报告摘要:Recently, Rosengren utilized an integral method to prove a number of conjectural identities found by Kanade and Russell. Using this integral method, we give new proofs to some double sum identities of Rogers-Ramanujan type. These identities were earlier proved by approaches such as combinatorial arguments or by using q-difference equations. Our proofs are based on streamlined calculations, which relate these double sum identities to some known Rogers-Ramanujan type identities with single sums. Moreover, we prove a conjectural identity of Andrews and Uncu which was earlier confirmed by Chern.
