This result has been known for long if additional regularity is assumed and in various other special cases, possibly for a limited range of values of . Here, -independence is proved in full generality. SN - 1687-2770 UR - https://doi.org/10.1155/2009/637243 DO - 10.1155/2009/637243 ID - Rabier2009 ER -
