Fixed points of reflections of compact convex sets and a characterization of state spaces of Jordan Banach algebras
Sh. A. Ayupov, N. J. Yadgorov
In the present article we prove a fixed point theorem for reflections of compact convex sets and give a new characterization of state space of JB-algebras among compact convex sets…
Algebras of unbounded operators over the ring of measurable functions and their derivations and automorphisms
S. Albeverio, Sh. A. Ayupov, A. A. Zaitov +1
In the present paper derivations and *-automorphisms of algebras of unbounded operators over the ring of measurable functions are investigated and it is shown that all L^0-linear d…

Sh. A. Ayupov, K. K. Kudaybergenov
Given a von Neumann algebra with a faithful normal semi-finite trace let be the algebra of all -measurable operators affiliated with We prove that if …
Non Commutative Arens Algebras and their Derivations
S. Albeverio, Sh. A. Ayupov, K. K. Kudaybergenov
Given a von Neumann algebra with a faithful normal semi-finite trace we consider the non commutative Arens algebra and the r…
