$(d,\sigma)$-twisted Affine-Virasoro superalgebras
Abstract
For any finite dimensional Lie superalgebra (maybe a Lie algebra) with an even derivation and a finite order automorphism that commutes with , we introduce the -twisted Affine-Virasoro superalgebra and determine its universal central extension . This is a huge class of infinite-dimensional Lie superalgebras. Such Lie superalgebras consist of many new and well-known Lie algebras and superalgebras, including the Affine-Virasoro superalgebras, the twisted Heisenberg-Virasoro algebra, the mirror Heisenberg-Virasoro algebra, the W-algebra , the gap- Virasoro algebras, the Fermion-Virasoro algebra, the BMS superalgebra, the planar Galilean conformal algebra. Then we give the classification of cuspidal -modules by using the weighting functor from -free modules to weight modules. Consequently, we give the classification of simple cuspidal -modules by using the -cover method. Finally, all simple quasi-finite modules over and are classified. Our results recover many known Lie superalgebra results from mathematics and mathematical physics, and give many new Lie superalgebras.
