Projections of Singular Vectors of Verma Modules over Rank 2 Kac–Moody Lie Algebras
We prove an explicit formula for a projection of singular vectors in the Verma module over a rank 2 Kac–Moody Lie algebra onto the universal enveloping algebra of the Heisenberg Lie algebra and of sl2 (Theorem 3). The formula is derived from a more general but less explicit formula due to Feigin, Fuchs and Malikov [Funct. Anal. Appl. 20 (1986), no. 2, 103–113]. In the simpler case of A1 the for...
متن کاملAlgorithms for affine Kac-Moody algebras
Weyl groups are ubiquitous, and efficient algorithms for them — especially for the exceptional algebras — are clearly desirable. In this letter we provide several of these, addressing practical concerns arising naturally for instance in computational aspects of the study of affine algebras or Wess-Zumino-Witten (WZW) conformal field theories. We also discuss the efficiency and numerical accurac...
متن کاملDual Graded Graphs for Kac-moody Algebras
Motivated by affine Schubert calculus, we construct a family of dual graded graphs (Γs,Γw) for an arbitrary Kac-Moody algebra g. The graded graphs have the Weyl group W of g as vertex set and are labeled versions of the strong and weak orders of W respectively. Using a construction of Lusztig for quivers with an admissible automorphism, we define folded insertion for a Kac-Moody algebra and obt...
متن کاملCase for support Unitary forms of Kac–Moody algebras and Kac–Moody groups
The proposed project is set in pure mathematics within the areas of infinite-dimensional Lie theory and geometric group theory. Its goal is to contribute to the structure theory of unitary forms (i.e., centralisers of Chevalley involutions) of Kac–Moody algebras and of Kac–Moody groups of indefinite type. The main emphasis of this project will be on finite-dimensional representations and on ide...
متن کاملKac–Moody Algebras and Controlled Chaos
Compactification can control chaotic Mixmaster behavior in gravitational systems with p–form matter: we consider this in light of the connection between supergravity models and Kac–Moody algebras. We show that different compactifications define “mutations” of the algebras associated with the noncompact theories. We list the algebras obtained in this way, and find novel examples of wall systems ...
