چکیده

In this paper the authors generalize a result of Vogan on irreducibility of standard modules for generic representations from real groups to p-adic ones whenever the inducing data is supercuspidal. They also prove injectivity for standard modules in this case. As applications, the authors prove a number of results relating the poles of intertwining operators and points of reducibility of induced representations to the poles of L-functions defined by the second author, module a conjecture on them whose validity for classical groups is also verified here. A result on certain real groups with applications in liftings of automorphic forms from classical groups to general linear groups via L-functions is also proved. 0 Elsevier, Paris RESUME. Dans cet article les auteurs generalisent un resultat de Vogan sur I’irreductibilite des modules standards pour les representations gtneriques des groupes reels vers les groupes p-adiques quand I’induite est supercuspidale. 11s prouvent Bgalement l’injectivite pour les modules standards dans ce cas. Les auteurs en deduisent quelques resultats reliant les poles des operateurs d’entrelacement et les points d’irreductibilite des representations induites, aux poles des fonctions L definies par le deuxibme auteur, modulo la validite d’une conjecture que l’on verifie ici pour les groupes classiques. On montre aussi un r&&at sur certains groupes reels avec applications aux correspondances des formes automorphes des groupes classiques vers les groupes lintaires via les fonctions L. 0 Elsevier, Paris

Irreducibility of the tensor product of Albeverio's representations of the Braid groups $B_3$ and $B_4$

‎We consider Albeverio's linear representations of the braid groups $B_3$ and $B_4$‎. ‎We specialize the indeterminates used in defining these representations to non zero complex numbers‎. ‎We then consider the tensor products of the representations of $B_3$ and the tensor products of those of $B_4$‎. ‎We then determine necessary and sufficient conditions that guarantee the irreducibility of th...

Monomial Irreducible sln-Modules

In this article, we introduce monomial irreducible representations of the special linear Lie algebra $sln$. We will show that this kind of representations have bases for which the action of the Chevalley generators of the Lie algebra on the basis elements can be given by a simple formula.

Irreducibility of fusion modules over twisted Yangians at generic point

With any skew Young diagram one can associate a one parameter family of ”elementary” modules over the Yangian Y(glN ). Consider the twisted Yangian Y(gN ) ⊂ Y(glN ) associated with a classical matrix Lie algebra gN ⊂ glN . Regard the tensor product of elementary Yangian modules as a module over Y(gN ) by restriction. We prove its irreducibility for generic values of the parameters.
