Suppose b 1 , ..., b n are self-adjoint elements in a finite von Neumann algebra M with trace { and define a map 9 from M to complex (n+1)-space by the formula 9(x)=({(x), {(b 1 x), ..., {(b n x)). Next let B denote the image of the positive unit ball of M under the map 9. B is called the spectral s
