Resumen:
The possibility of propagating Korteweg-de Vries solitons in a superfluid 4He film and in a superfluid 4He film overlayed by a 3He film is discussed. Various dispersive and nonlinear contributions to the equation for the nonlinear modes of the films are analyzed. Conditions depending on the thickness of the films are obtained for the propagation of throughlike and bumplike solitons.
