Classification of simple modules with finite-dimensional weight spaces for the N = 2 Ramond algebra

Abstract

In this paper, we classify all simple weight modules with finite-dimensional weight spaces over the $N=2$ Ramond algebra. Any such module $V$ is either a simple highest weight module or a simple lowest weight module, or a simple cuspidal module with $\mathrm{b}(V)\le 2$.
