摘 要：For various purposes, in addition to the traditional theories of modules and twisted modules, the theories of quasi modules, ϕ-coordinated modules, and twisted ϕ-coordinated modules were developed for quantum vertex algebras including vertex super-algebras. The most general theory is that of twistedϕ-coordinated quasi modules. In this talk, as an illustrating example we shall use a family of infinite-dimensional Lie superalgebras, introduced by L¨u,You, and Zhao, called the (d, σ)-twisted affine-Virasoro Lie superalgebras, to give a natural connection of this family of Lie super-algebras with N-graded conformal vertex superalgebras in terms of (ordinary) modules, ϕ-coordinatedmodules, and twisted ϕ-coordinated modules. This talk is based on joint work with Kaiming Zhao.
