Isometric decomposition conjecture for von Neumann factors
Isometric decomposition conjecture for von Neumann factors
Let be a type- or type- factor acting on a separable Hilbert space, and let denote its essential numerical range. An isometric decomposition is a sequence of isometries in satisfying
Let be the specified set occurring in the source. Isometric decomposition conjecture. If satisfies and satisfies , then there exists an isometric decomposition of such that
The surrounding section presents this as a possible extension of operator-pinning results from to type- and type- factors; the supplied text gives no resolution.
