报告题目：On root graded Lie algebras and elliptic Lie algebras
报告摘要：Root graded Lie algebras were first studied by Berman-Moody in 1990’s, the elliptic Lie algebras are root graded Lie algebras, and the elliptic Lie algebras of maximal type are also the nullity two extended affine Lie algebras, which are generalization of the affine Kac-Moody Lie algebras. It is well known that the restricted modules for any untwisted affine Kac-Moody Lie algebra are isomorphic to the modules for the associated affine vertex algebra, while the restricted modules for the twisted affine Kac-Moody Lie algebra are isomorphic to the twisted modules for the affine vertex algebra. In this talk we will recall the classification of elliptic Lie algebras of maximal type, and the notion of γvertex algebra and equivariantφcoordinated quasi-modules for vertex algebras. I will then claim that there exist a vertex algebra V associated with any elliptic Lie algebra of maximal type and an automorphism group G of V equipped with a linear characterχ, such that the category of restricted modules for the elliptic Lie algebra is isomorphic to the category of (G, χ)-equivariant χ-coordinated quasi modules for the vertex algebra V.
