چکیده
Let $\mathfrak {g}$ be a complex simple Lie algebra. We classify the parabolic subalgebras {p}$ of such that nilradical has commutative polarisation. The answer is given in terms Kostant cascade. It requires also notion an optimal and some properties abelian ideals Borel subalgebra .

On the Kostant Conjecture for Clifford Algebras
Let g be a complex simple Lie algebra, and h ⊂ g be a Cartan subalgebra. In the end of 1990s, B. Kostant defined two filtrations on h, one using the Clifford algebras and the odd analogue of the Harish-Chandra projection hcodd : Cl(g) → Cl(h), and the other one using the canonical isomorphism ȟ = h∗ (here ȟ is the Cartan subalgebra in the simple Lie algebra ǧ corresponding to the dual root syst...
متن کاملKostant ’ s problem and parabolic subgroups Johan
Let g be a finite dimensional complex semi-simple Lie algebra with Weyl group W and simple reflections S. For I ⊆ S let g I be the corresponding semi-simple subalgebra of g. Denote by W I the Weyl group of g I and let w • and w I • be the longest elements of W and W I , respectively. In this paper we show that the answer to Kostant's problem, i.e. whether the universal enveloping algebra surjec...
متن کاملA generalization of the Kostant-Macdonald identity.
Let X be a smooth projective variety admitting an algebraic vector field V with exactly one zero and a holomorphic C(*)-action lambda so that the condition dlambda(t).V = t(p)V holds for all t in C(*). The purpose of this note is to report on a product formula for the Poincaré polynomial of X which specializes to the classical identity [Formula: see text] when X is the flag variety of a semisim...
متن کاملOn the Nonlinear Convexity Theorem of Kostant
A classical result of Schur and Horn [Sc, Ho] states that the set of diagonal elements of all n x n Hermitian matrices with fixed eigenvalues is a convex set in IRn. Kostant [Kt] has generalized this result to the case of any semisimple Lie group. This is often referred to as the linear convexity theorem of Kostant: picking up the diagonal of a Hermitian matrix is a linear operation. This resul...
متن کاملVariations on the themes of Kostant
Let g be a complex semisimple Lie algebra, and let G be a complex semisimple group with trivial center whose root system is dual to that of g. We establish a graded algebra isomorphism H q (Xλ,C) ∼= Sg e/Iλ, where Xλ is an arbitrary spherical Schubert variety in the loop Grassmannian for G, and Iλ is an appropriate ideal in the symmetric algebra of g, the centralizer of a principal nilpotent in...
