报告摘要:

In this talk, we provide a homomorphism of algebras from the quantum group U^+ to the corresponding quantum cluster algebra A_q with principal coefficients. As a by-product, we show that the quantum cluster variables arising from one-step mutations from the initial cluster variables satisfy the (high order) quantum Serre relations in A_q. This talk is based on the join work with Changjian Fu.
