Gleason’s Theorem for non-separable Hilbert spaces: Extended abstract

The probelm of generalizing Gleason’s theorem to the non separable case arose in correspondence with Paul Chernoff. I am very grateful to him for suggesting this charming problem to me. Let H be a Hilbert space. The coefficient field K of H can be either the reals or the complexes. We let P(H) denote the collection of all closed subspaces of H. A Gleason measure on H is a map μ : P(H) → [0, 1] ...
