Repeat the exer- cise in homology, for cor G×K H×K and tr G×K H×K (in homology, the hypothesis that G be finite can be supressed, but of course we need [G : H ] < ∞ for the

COROLLARY 3.7. Assume that the radical of G is simply connected and that G has a maximal connected semisimple subgroup with finite center. Then G has a finite covering with

In particular, Theorem 1.2 shows that the problem of approximating compact Kähler manifolds with projective ones has a positive answer in the case of smooth tori families..

In this paper we shall generalize Gerstenhaber’s result to reductive Lie algebras and simply connected semisimple algebraic groups, both over algebraically closed

“nice pairs”, for which he proved that λ p s > 0 for any s ∈ p semisimple. If the roots of the b-functions of a module M F are not integers, as in the example of

Linear algebraic groups and their homogeneous spaces have been thoroughly in- vestigated; in particular, the Chow ring of a connected linear algebraic group G over an

A first crucial fact is that ψ = ϕ| U ◦ exp is a G-invariant function of positive type on u (for the underlying abelian group structure) and is extremal under such functions
