|Abstract: In this talk, we will introduce several classes of non-graded modules for the Virasoro algebra and affine Lie algebras. Non-graded modules include some restricted modules, which are in some sense the most important modules for the representation theory of vertex algebras, and non-restricted modules. We will describe the structures and the irreducible conditions of these modules constructed by us.|
