| Oct 4, 2013 at 3:26 | comment | added | Terry Tao | In general, the U and V here will not be unique (this can be seen by a simple dimension counting argument). The known proofs of the above statement are quite indirect and non-constructive; they prove that U and V exist, but do not give an explicit recipe for finding such a U and V. | |
