Abstract : The existence of periodic progressing waves of finite amplitude on the surface of a heavy liquid of finite or infinite depth is investigated. It is first shown that the problem is equivalent to solving a nonlinear integral equation. The existence of solutions of the nonlinear integral equation is then proved by expanding the solutions in a perturbation series about the solution of the linearized integral equation, and showing that the perturbation series is convergent for waves of sufficiently small amplitude. The first few terms of the perturbation series are calculated. The use of perturbation series for solving nonlinear integral equations is discussed. (Author)
