报告摘要
Based on a cluster category CM(A), we construct compatible pairs of matrices (B(T), L(T)) from a cluster tilting object T in CM(A). We show that
1) when the matrix L is constructed from certain special cluster tilting objects , L computes quasi-commutation rules for quasi-commuting quantum minors.
2) Mutation of (B(T), L(T)) is consistent with mutation of cluster tilting objects.
The goal of this talk is to explain how 1) and 2) lead to a quantum cluster algebra structure on a quantum Grassmannian and thus a categorification of the quantum Grassmannian cluster algebra.
