Instability of capillary waves in free thin films
For the description of waves in a thin film, the authors construct the Hamiltonian of asymptotically nonlinear system of equations. Moreover, no restrictions are imposed on the deviation of the film middle surface from the unperturbed one. The authors investigate the stability of pure capillary exact periodic solutions of this system.
