Character Values, Schur Indices and Character Sheaves
In this paper we are concerned with the problem of determining the character values and Schur indices of a finite group of Lie type over Fq. We show that (under some conditions on q) these values lie in the ring of algebraic integers generated by (1 + ñq)/2 and roots of unity of order prime to q. Furthermore, we determine the Schur indices for some of the (nonrational) unipotent characters in ...
متن کاملGeneric Character Sheaves on Disconnected Groups and Character Values
We relate a generic character sheaf on a disconnected reductive group with a character of the rational points of the group over a finite field extending a known result in the connected case.
متن کاملCharacter Sheaves and Generalizations
1. Let k be an algebraic closure of a finite field Fq. Let G = GLn(k). The group G(Fq) = GLn(Fq) can be regarded as the fixed point set of the Frobenius map F : G −→ G, (gij) 7→ (g q ij). Let Q̄l be an algebraic closure of the field of l-adic numbers, where l is a prime number invertible in k. The characters of irreducible representations of G(Fq) over an algebraically closed field of characteri...
متن کاملParabolic Character Sheaves
0.1. Let G be a connected reductive algebraic group over an algebraically closed field k. Let Z be the variety (of the same dimension as G) consisting of all pairs (P, gUP ) where P runs through a fixed conjugacy class P of parabolics of G and gUP ∈ G/UP (UP is the unipotent radical of P ). Now G acts on Z by h : (P, gUP ) 7→ (hPh , hghUhPh−1). In this paper we study a class of simple G-equivar...
متن کاملCharacter Sheaves , Ii 3
Let G be a connected reductive algebraic group over an algebraically closed field k. Let Z be the algebraic variety consisting of all triples (P, P , UP ′gUP ) where P, P ′ run through some fixed conjugacy classes of parabolics in G and g is an element of G that conjugates P to a parabolic in a fixed ”good” relative position y with P ′ (here UP , UP ′ are the unipotent radicals of P, P ). The v...
