Nonpositively curved metric in the positive cone of a finite von Neumann algebra
(Oxford University Press, 2006-08)
In this paper we study the metric geometry of the space Σ of positive invertible elements of a von Neumann algebra. A with a finite, normal and faithful tracial state T. The trace induces an incomplete Riemannian metric ...
