Sea G un grupo de Lie simple de tipo no compacto, conexo y con centro finito. Fijemos un subgrupo compacto maximal K de G. Sea p una representación unitaria e irreducible de G y sea H un subgrupo reductivo cerrado de G. ...

For a semisimple Lie group G satisfying the equal rank condition, the most basic family of unitary irreducible representations is the discrete series found by Harish-Chandra. In this paper, we study some of the branching ...

En este trabajo estudiamos la continuación meromórfa del núcleo de la resolvente del Laplaciano en varias situaciones. En primer lugar se considera el caso de los espacios simétricos de curvatura negativa G/K y el Laplaciano ...

Until a couple of years ago, the only known examples of Lie groups admitting left-invariant metrics with negative Ricci curvature were either solvable or semisimple.We use a general construction from a previous article of ...

Este trabajo es sobre la clasificación, módulo equivalencia, de las representaciones irreducibles de dimensión finita de álgebras de Lie complejas semisimples de dimensión finita. El Teorema del peso máximo describe a las ...

We construct many examples of Lie groups admitting a left-invariant metric of negative Ricci curvature. We study Lie algebras which are semidirect products l= (a⊕ u) ⋉ n and we obtain examples where u is any semisimple ...

We present a family of networks whose local interconnection topologies are generated by the root vectors of a semi-simple complex Lie algebra. Cartan classification theorem of those algebras ensures those families of ...
