1. Representações de hiperálgebras de laços e álgebras de multi-correntes / Representations of hyper loop algebras and multi curret algebras
Este trabalho é dedicado ao estudo de alguns assuntos da teoria de representações de certas álgebras que podem ser vistas como generalizações do conceito de álgebras de Kac-Moody am. De modo geral, o trabalho é dividido em duas partes: na primeira delas, abordamos questões sobre as representações de dimensão finita das hiperálgebras de laços to

2. Álgebras de cluster e teoria de representações / Cluster algebras and representation theory
Na presente dissertação estudamos dois exemplos de relacionamento da teoria de álgebras de cluster com teoria de representações. A saber, estudamos os principais resultados dos artigos [5, 26]. O primeiro é uma relação entre álgebras de cluster e representações de certos quivers com relações que também estão relacionadas com triangulações de

5. Vertex algebras, Kac-Moody algebras, and the Monster
It is known that the adjoint representation of any Kac-Moody algebra A can be identified with a subquotient of a certain Fock space representation constructed from the root lattice of A. I define a product on the whole of the Fock space that restricts to the Lie algebra product on this subquotient. This product (together with a infinite number of other produ

6. Spinor representations of affine Lie algebras
Let [unk] be an infinite-dimensional Kac-Moody Lie algebra of one of the types Dl+1(2), Bl(1), or Dl(1). These algebras are characterized by the property that an elimination of any endpoint of their Dynkin diagrams gives diagrams of types Bl or Dl of classical orthogonal Lie algebras. We construct two representations of a Lie algebra [unk], which we call spi

7. Dedekind's η-function and the cohomology of infinite dimensional Lie algebras
We compute the cohomology of certain infinite dimensional Lie algebras which are subalgebras of Lie algebras introduced by Moody and Kac. We note a relation between our results and the cohomology of loop spaces of compact groups. Finally, we derive, by Euler-Poincaré, identities of Macdonald for powers of the Dedekind η-function.

8. Modular invariant representations of infinite-dimensional Lie algebras and superalgebras
In this paper, we launch a program to describe and classify modular invariant representations of infinite-dimensional Lie algebras and superalgebras. We prove a character formula for a large class of highest weight representations L(λ) of a Kac-Moody algebra [unk] with a symmetrizable Cartan matrix, generalizing the Weyl-Kac character formula [Kac, V. G. (1

9. Laplace operators of infinite-dimensional Lie algebras and theta functions
Until recently, the generalized Casimir operator constructed by Kac [Kac, V. G. (1974) Funct. Anal. Appl. 8, 68-70] has been the only known element of the center of a completion of the enveloping algebra of a Kac-Moody algebra. It has been conjectured [Deodhar, V. V., Gabber, O. & Kac, V. G. (1982) Adv. Math. 45, 92-116], however, that the image of the Haris

10. A new family of algebras underlying the Rogers-Ramanujan identities and generalizations
The classical Rogers-Ramanujan identities have been interpreted by Lepowsky-Milne and the present authors in terms of the representation theory of the Euclidean Kac-Moody Lie algebra A1(1). Also, the present authors have introduced certain “vertex” differential operators providing a construction of A1(1) on its basic module, and Kac, Kazhdan, and we have
