摘 要: | In view of V≠O, the relation (P. 6, line 16) should be replaced by with f_0=1/f, and(3.12) should be changed to the form ds~2=1/U~2sum from a=1 to n-1 ((dx~a)~2+V~2(dx~n)~2]) where V and U are connected by the relation (*). After altering the formulation in such a way, we are justified to consider the limiting case f_0=0, which has
