Abstract

In this paper, we construct a novel class of simple modules for the WW-algebra W(2,2)W(2,2). Our approach involves taking tensor products of finitely many non-weight simple modules Ω(λ,α,h)\Omega(\lambda,\alpha,h) with an arbitrary simple restricted module. We provide a necessary and sufficient condition for these modules to be simple, and subsequently determine their isomorphism classes. Through a comparative analysis with other known simple modules in the literature, we establish that these constructed modules are generically new.
