. Let D be a quaternion algebra over R , G = GL n ( D ) and H = GL n ( C ) regarded as a subgroup of G . For a character χ on C × , we say that an irreducible smooth admissible moderate growth representation π of G is χ H -distinguished if Hom H ( π, χ ◦ det H ) 6 = 0. We compute the root number of a χ H -distinguished representation π twisted by the representation induced from χ . This proves an Archimedean analogue of the conjecture by Prasad and Takloo-Bighash (J. Reine Angew. Math., 2011…

1.1. Epsilon dichotomy. Let E/F be a quadratic field extension of local nonarchimedean fields of characteristic zero and η the quadratic character of F× attached to E via the local class field

Symplectic local root numbers, central critical L-values, and restriction problems in the representation theory of classical groups

We consider several questions about restriction of representations of classical and metaplectic groups over local and global fields to subgroups, extending considerably the scope of the earlier work

Bruhat filtrations and Whittaker vectors for real groups

In this paper we continue earlier work of Bruhat, Jacquet, and Shalika on Whittaker models for smooth representations of real groups. We prove exactness in a certain category of such smooth

Exceptional Lie groups

We describe simply connected compact exceptional simple Lie groups in very elementary way. We first construct all simply connected compact exceptional Lie groups G concretely. Next, we find all
