Abstract: Abstract In this paper, we give an affirmative answer to Tingley's problem between finite von Neumann algebras. To do this, we see that every norm closed proper face of the unit ball of a unital… read more here.

Abstract: We prove the conjugacy of Sylow 2-subgroups in pseudofinite Mc (in particular linear) groups under the assumption that there is at least one finite Sylow 2-subgroup. We observe the importance of the pseudofiniteness assumption by… read more here.
