title: Marangoni convection on an inhomogeneous substrate.
abstract: We consider an inhomogeneous substrate for Marangoni convection. The inhomogeneity shows up in a nonuniform temperature distribution which we model by a periodic variation. The response can exhibit parametric resonance. Both resonant and nonresonant responses are considered and a possible strong effect on wave number selection indicated.
