Graded torsion-free 𝔰𝔩2(ℂ)-modules of rank 2
Abstract
In this paper, we explore the possibility of endowing simple infinite-dimensional [Formula: see text]-modules by the structure of graded modules. The gradings on the finite-dimensional simple modules over simple Lie algebras have been studied in 7, 8.
