Commutativity of projections and characterization of traces on von Neumann algebras
A. M. Bikchentaev N. G. Chebotarev Research Institute of Mathematics and Mechanics, Kazan State University, Kazan
Abstract:
We find new necessary and sufficient conditions for the commutativity of projections in terms of operator inequalities. We apply these inequalities to characterize a trace on von Neumann algebras in the class of all positive normal functionals. We obtain some characterization of a trace on von Neumann algebras in terms of the commutativity of products of projections under a weight.
Keywords:
Hilbert space, von Neumann algebra, spectral theorem, weight, trace, normal functional, bounded linear operator, projection, operator inequality, commutativity of operators.
