Complete families of commuting functions for coisotropic Hamiltonian actions
Autor: E. B. Vinberg, Oksana S. Yakimova
Publikováno v: Advances in Mathematics. 348:523-540
Let G be an algebraic group defined over a field F of characteristic zero with g = Lie G . The dual space g ⁎ equipped with the Lie–Poisson bracket is a Poisson variety and each irreducible G-invariant subvariety X ⊂ g ⁎ carries the induced P

On Some Free Algebras of Automorphic Forms
Autor: E. B. Vinberg
Publikováno v: Functional Analysis and Its Applications. 52:270-289
It is proved that, for n = 8, 9, 10, the natural algebra of automorphic forms of the group O+2,n(ℤ) acting on the n-dimensional symmetric domain of type IV is free, and the weights of generators are found. This extends results obtained in the autho

Degeneration of Horospheres in Spherical Homogeneous Spaces
Autor: E. B. Vinberg, Simon Gindikin
Publikováno v: Functional Analysis and Its Applications. 52:83-92
Horospheres for an action of a semisimple algebraic group G on an affine variety X are the generic orbits of a maximal unipotent subgroup U ⊂ G or, equivalently, the generic fibers of the categorical quotient of the variety X by the action of U, wh

Moduli algebras of some non-semiquasihomogeneous singularities
Autor: E. B. Vinberg, M. A. Jibladze, A. G. Elashvili
Publikováno v: Functional Analysis and Its Applications. 51:86-97
Under some additional restrictions we find dimensions and bases of moduli algebras of isolated singularities of polynomials in n variables that are sums of n monomials of equal weighted degrees and one monomial of lower degree.
