Abstract
We study the kinetic roughening described by a linear diffusion equati on on an initially rough substrate. We show analytically that it is no t possible to write a general scaling relation valid for rough substra tes. However, for a particular substrate generated by the same linear growth process, we can write a scaling relation similar to the relatio n valid for Bat substrates, with the same growth and roughness exponen ts. Numerical simulations in a solid-on-solid model with surface relax ation, for d=1, supports the scaling relation and the exponents.
