It is shown in this paper that the scaling properties of an N-component Kardar-Parisi-Zhang equation in the large N limit (spherical limit) can be obtained by solving the mode-coupling equation. The full scaling functions and the critical exponents in the large N limit are obtained exactly by solving the mode-coupling equation numerically. The dynamic exponent z is found to be 1.615 at dimension d=2, very close to the value obtained by numerical simulation of growth process, but z remains less than 2 in any finite dimension, suggesting the existence of a strong coupling regime for any finite dimension. © 1994 The American Physical Society.
