This will be an expanded and updated version of the second half of my talk at ICM2002 covering my three joint works with Ken Dykema on the subject as well as a new joint work with my PhD student Hanne Schultz on constructing spectral subspaces for any operator in any II1 factor. A preliminary version (98 pp) is available at Hanne Schultz' home page.
