Abstract For a simple Lie algebra, L, over the complex numbers we study generalized Verma modules induced from modules which are torsion-free over a parabolic sub-algebra and the irreducible… Expand

We study representations of the Loop Kac-Moody Lie algebra 𝔤 ⊗A, where 𝔤 is any Kac-Moody algebra and A is a ring of Laurent polynomials in n commuting variables. In particular, we study… Expand

Remarkable subalgebras of the Yangian for gl_n called the shifted Yangians were introduced in a recent work by Brundan and Kleshchev in relation to their study of finite W-algebras. In particular, in… Expand
