The Nash-Moser Theorem of Hamilton and rigidity of finite dimensional nilpotent Lie algebras

Alfredo Brega, Leandro Cagliero, Augusto Chaves Ochoa

We apply the Nash-Moser theorem for exact sequences of R. Hamilton to the context of deformations of Lie algebras and we discuss some aspects of the scope of this theorem in connec…

The image of the Lepowsky homomorphism for the group $F_{4}$

Alfredo Brega, Leandro Cagliero, Juan Tirao

Let $G_{o}$ be a semisimple Lie group, let $K_{o}$ be a maximal compact subgroup of $G_{o}$ and let $k \subset g$ denote the complexification of their Lie algebras. L…

LU-decomposition of a noncommutative linear system and Jacobi polynomials

Alfredo Brega, Leandro Cagliero

In this paper we obtain the LU-decomposition of a noncommutative linear system of equations that, in the rank one case, characterizes the image of the Lepowsky homomorphism $U(\lie…
