Jordan classes and Lusztig strata in disconnected reductive groups
نویسندگان
چکیده
Let G be a non-connected reductive algebraic group over an algebraically closed field K and let D connected component of G. We investigate the Jordan classes we obtain description regular part closure class in terms induction G∘-orbits. use this result to show that Lusztig strata are locally closed.

Lusztig Induction and `-blocks of Finite Reductive Groups
We present a unified parametrisation of `-blocks of quasi-simple finite groups of Lie type in non-defining characteristic via Lusztig’s induction functor in terms of eJordan-cuspidal pairs and e-Jordan quasi-central cuspidal pairs.
متن کاملOn Unipotent Supports of Reductive Groups With a Disconnected Centre
Let G be a simple algebraic group defined over a finite field of good characteristic, with associated Frobenius endomorphism F. In this article we extend an observation of Lusztig, (which gives a numerical relationship between an ordinary character of GF and its unipotent support), to the case where Z(G) is disconnected. We then use this observation in some applications to the ordinary characte...
متن کاملChern classes of compactifications of reductive groups
In this paper, I construct noncompact analogs of the Chern classes of equivariant vector bundles over complex reductive groups. Then “Chern classes” of the tangent bundle are used to carry over to the case of an arbitrary reductive group some of the well-known results that hold for a complex torus. One of the results of this paper is a formula for the Chern classes of all regular equivariant co...
متن کاملDimensions of Newton Strata in the Adjoint Quotient of Reductive Groups
In [Cha00] Chai made a conjecture on the codimensions of Newton strata in Shimura varieties, which then led Rapoport [Rap05] to his conjecture on dimensions of affine Deligne-Lusztig varieties inside affine Grassmannians. The main goal of this paper is to show that exactly the same codimensions arise in a simpler context, that of the Newton stratification in the adjoint quotient of a reductive ...
متن کاملOn Disconnected Groups
Throughout this paper, G denotes a fixed, not necessarily connected, reductive algebraic group over an algebraically closed field k. This paper is a part of a series [L9] which attempts to develop a theory of character sheaves on G. The numbering of the sections and references continues that of the earlier Parts. Section 23 is a generalization of results in [L3, II,§7]. It is a preparation for ...
