mappings Metrics on projections of the von Neumann algebra associated with tracial functionalsWe investigate two metricson projections of the von
Neumann algebra associated with tracial

The solution of a mixed boundary value problem for the Laplace equation in a multiply connected domain of the
Dirichlet condition or the form of the
Neumann condition. This analytic method gives highly accurate results
Rearrangements of Tripotents and Differences of Isometries in Semifinite von Neumann AlgebrasLet τ be a faithful normal semifinite trace on a von

On the problem of boundedness of a signed measure on projections of a von Neumann algebraLet M be a von
Neumann algebra and Mn be the set of all orthogonal projections in M. We call a

On finite-sheeted covering mappings onto solenoidsWe study limit
mappings from a solenoid onto itself. It is shown that each equivalence class
