Outer actions of finite groups on prime C*-algebras
Costel Peligrad
An action of a compact, in particular finite group on a C*-algebra is called properly outer if no automorphism of the group that is distinct from identity is implemented by a unita…
Properly Outer and Strictly Outer Actions of Finite Groups on Prime C*-algebras
Costel Peligrad
An action of a compact, in particular finite group on a C*-algebra is called properly outer if no automorphism of the group that is distinct from identity is implemented by a unita…
Duality for compact group actions on operator algebras and applications: irreducible inclusions and Galois correspondence
Costel Peligrad
We consider compact group actions on C*- and W*- algebras. We prove results that relate the duality property of the action (as defined in the Introduction) with other relevant prop…
Invariant subspaces of generalized Hardy algebras associated with compact abelian group actions on W*-algebras
Costel Peligrad
We consider an action of a compact group whose dual is archimedean linearly ordered or a direct product (or sum) of such groups on a von Neumann algebra, M. We define the generaliz…
Compact Group Actions On Operator Algebras and Their Spectra
Costel Peligrad
We consider a class of dynamical systems with compact non abelian groups that include C*-, W*- and multiplier dynamical systems. We prove results that relate the algebraic properti…
Invariant subspaces of algebras of analytic elements associated with periodic flows on W*-algebras
Costel Peligrad
We consider an action of the circle group, T on a von Neumann algebra, M. Similarly to the case when the algebra of essentially bounded functions on T is acted upon by translations…
