Classification of Simple Cuspidal Modules Over a Lattice Lie Algebra of Witt Type
Published online by Cambridge University Press: 13 January 2020
Abstract
Let $W_{\unicode[STIX]{x1D70B}}$ be the lattice Lie algebra of Witt type associated with an additive inclusion $\unicode[STIX]{x1D70B}:\mathbb{Z}^{N}{\hookrightarrow}\mathbb{C}^{2}$ with $N>1$. In this article, the classification of simple $\mathbb{Z}^{N}$-graded $W_{\unicode[STIX]{x1D70B}}$-modules, whose multiplicities are uniformly bounded, is given.
