Separation Theorems for Group Invariant Polynomials

The Journal of Geometric Analysis, 2017
The present article investigates the existence of separation theorems by polynomials. This is a variation of the complex Hahn-Banach separation theorem, which establishes that if \(K\subset\mathbb C^n\) is a closed convex set and \(z\) is a point in \(\mathbb C^n\setminus K\), then there exists a complex linear form \(f\) with sup\(_{w\in K}\{\mathrm ...

Invariant subrings of separable algebras

Israel Journal of Mathematics, 1973
This paper gives a necessary and sufficient condition that the ring of invariants of every group of automorphisms of every projective, separable, commutative algebra over a given commutative ring is itself a union of separable, projective subalgebras.

Invariance for Systems with Separated Motions

IFAC Proceedings Volumes, 2001
Abstract The paper presents the methods of synthesis of invariant dynamic systems on the basis of the theory of systems with separated motions with usage of deep feedback and discontinuous controls. Usage of this class of feedback with padding hierarchical structure of synthesized controls allows: to expand the class of invariant systems as ...

Separable and vector groups whose projectively invariant subgroups are fully invariant

Siberian Mathematical Journal, 2009
Summary: We study the Abelian groups all of whose projectively invariant subgroups are fully invariant. We describe the separable and vector groups with this property.

Separability and invariance in nonrelativstic and relativistic quantum mechanics

Theoretical and Mathematical Physics, 1975
We have shown that good separability of the Hamiltonian in time, i.e.,τγ-separability, is sufficient to formulate time-dependent scattering theory. The property ofτγ-separability, extended to all the operators of Galileo or Poincare transformations, guarantees corresponding invariance of the scattering operators.
