Abstract
We find an exact formula of Gelfand-Kirillov dimensions for the infinite-dimensional explicit irreducible \(\mathfrak{s}\mathfrak{l}\)(n, \(\mathbb{F}\))-modules that appeared in the ℤ2-graded oscillator generalizations of the classical theorem on harmonic polynomials established by Luo and Xu. Three infinite subfamilies of these modules have the minimal Gelfand-Kirillov dimension. They contain weight modules with unbounded weight multiplicities and completely pointed modules.
We’re sorry, something doesn't seem to be working properly.
