WebJul 1, 1999 · Gleason's theoremfor R3says that if fis a nonnegative function on the unit sphere with the property that f(x)+f(y)+f(z) is a fixed constant, the weightof f, for each triple x,y,zof mutually orthogonal unit vectors, then fis a quadratic form. That is f(x) = a11x12+a22x22+a33x32+2a12x1x2+2a13x1x3+2a23x2x3. WebThe conclusion of our theorem is the same as that of Gleason’s theorem. The extreme simplicity of the proof in comparison to Gleason’s proof is due to the fact that the domain of generalized probability measures is sub-stantially enlarged, from the set of projections to that of all effects. The statement of the present theorem also extends to

If f is a bounded real-valued function on the unit sphere of an inner product space of dimension at least 3, and f is a frame function on each 3-dimensional subspace, then f(x)=B(x, x) for some bounded Hermitian form B. That is, f is a quadratic form. Theorem 1 is the part of Gleason’s theorem that requires the overwhelm- lowest term infinite geometric series
