Title: Semi-groups arising from modules of affine Lie algebras
Speaker: 郜云教授 （中国科技大学）
In the study of representations of extended affine Lie algebras, we construct modules based on the affine Lie algebras and notice that the modules can be served as Lie algebras coordinated Laurant polynomials twisted with a semi-group.
