Löwner's theorem and the differential geometry of the space of positive operators
Let A be a untel C*-algebra and G+ the space of all positive invertible elements of A. In this largely expository paper we collect several geometrical features of G+ which relate its structure with that of Riemannian manifolds with non positive curvature. The main result of the paper is the equivale...
