Title:  On locally repeated values of certain arithmetic functions. I. (In English)
Source:  J. Number Theory 21, 319-332 (1985).
Review:  It is shown that, for certain integer-valued arithmetic functions f, the equation n+f(n) = m+f(m) has infinitely many solutions with n\ne m. Let \nu(n) denote the number of distinct prime factors of n. Then, for f = \nu, a lower bound for the number of solutions n,m \leq x is given.
