The Haagerup problem on subadditive weights on $W^*$-algebras
A. M. Bikchentaev Research Institute of Mathematics and Mechanics, Kazan (Volga region) Federal University, Kazan, Russia
Abstract:
In year 1975 U. Haagerup posed the following question: Whether every normal subadditive weight on a $W^*$-algebra is sigma-weakly lower semicontinuous? Here we positively answer this question in a particular case of abelian $W^*$-algebras and present a general form of normal subadditive weights on these algebras.
Keywords:
$C^*$-algebra, $W^*$-algebra, subadditive weight, measurable function.
