Irreducible tensor product modules over the -algebra
Abstract
In this paper, we construct a class of non-weight modules over the -algebra by taking tensor products of modules with restricted modules . Then, we give the necessary and sufficient conditions for the irreducibility of such tensor product modules and determine the conditions under which two irreducible tensor product modules are isomorphic. These non-weight modules are different from known non-weight modules. Finally, we transform some tensor product modules into induced modules from modules of certain subalgebras over the -algebra . And the conditions for these induced modules to be irreducible are determined by applying the established results.
