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…
Convergence of series of conditional expectations
Magda Peligrad, Costel Peligrad
This paper deals with rates of convergence in the strong law of large numbers, in the Baum-Katz form, for partial sums of Banach space valued random variables. The results are then…
On the local limit theorems for lower psi-mixing Markov chains
Florence Merlevède, Magda Peligrad, Costel Peligrad
In this paper we investigate the local limit theorem for additive functionals of nonstationary Markov chains that converge in distribution. We consider both the lattice and the non…
On the local limit theorems for psi-mixing Markov chains
Florence Merlevède, Magda Peligrad, Costel Peligrad
In this paper we investigate the local limit theorem for additive functionals of a nonstationary Markov chain with finite or infinite second moment. The moment conditions are impos…
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…
