WebbNONDIVERGENCE OF REDUCTIVE GROUP ACTION ON HOMOGENEOUS SPACES HAN ZHANG AND RUNLIN ZHANG Abstract. Let G/Γ be the quotient of a semisimple Lie group Gby its arithmetic lattice. Let H be a reductive algebraic subgroup of Gacting on G/Γ. The question we are interested in is whether there is a compact set of G/Γ that intersects … WebbINTRODUCTION TO REDUCTIVE GROUP SCHEMES OVER RINGS P. GILLE In construction 1. Introduction The theory of reductive group schemes is due to Demazure and Grothendieck and was achieved fty years ago in the seminar SGA 3. Roughly speaking it is the theory of reductive groups in family focusing to subgroups and classi cation issues.

Parametrization of the image of normalized intertwining operators. the business marketWebbWith the standard definition of a reductive algebraic group, a complex connected subgroup of GL (V) is reductive if and only if it is preserved by conjugate transpose under some choice of basis. I think that's one of Knapp's definitions. A nonconnected subgroup can be preserved by a conjugate transpose without being reductive. the business misinformation crowdfundedIn mathematics, a reductive group is a type of linear algebraic group over a field. One definition is that a connected linear algebraic group G over a perfect field is reductive if it has a representation with finite kernel which is a direct sum of irreducible representations. Reductive groups include some of the most … Visa mer A linear algebraic group over a field k is defined as a smooth closed subgroup scheme of GL(n) over k, for some positive integer n. Equivalently, a linear algebraic group over k is a smooth affine group scheme over k. Visa mer GLn and SLn A fundamental example of a reductive group is the general linear group $${\displaystyle {\text{GL}}_{n}}$$ of invertible n × n matrices over a field k, for a natural number n.
