A Classification of Indecomposable sl2(image)-Modules and a Conjecture of Kac on Irreducible Modules over the Virasoro Algebra Original Research Article

In this paper, we first give a classification of indecomposable Harish-Chandra sl2(image)-modules, then discuss a conjecture of Kac on irreducible module over the Virasoro algebra, proving that the conjecture is true under a certain condition.
