Abstract:We construct a class of non-weight modules over the affine-Virasoro algebra of type $A_1$ by taking tensor products of a finite number of irreducible $U(h)$-free modules with irreducible highest weight modules. We show that these tensor product modules are irreducible, and determine the necessary and sufficient conditions for such two modules to be isomorphic. We also compare these modules with other known non-weight modules, showing that these irreducible modules are new. This is a joint work with Qiufan Chen.
