Martingales associated with strongly quasi-invariant states
Ameur Dhahri, Chul Ki Ko, Hyun Jae Yoo
We discuss the martingales in relevance with -strongly quasi-invariant states on a -algebra , where is a separable locally compact group of -automorphism…

Group of automorphisms for strongly quasi invariant states
Ameur Dhahri, Chul Ki Ko, Hyun Jae Yoo
For a -automorphism group on a - or von Neumann algebra, we study the -quasi invariant states and their properties. The -quasi invariance or -strongly quasi in…
