title: Coupled nonequilibrium growth equations: self-consistent mode coupling using vertex renormalization
abstract: We find that studying the simplest of the coupled nonequilibrium growth equations of Barabasi by self-consistent mode coupling requires the use of dressed vertices. Using the vertex renormalization, we find a roughening exponent which already in the leading order is quite close to the numerical value.
