    Resumen Estudiamos una clase de problemas de valor inicial para ecuaciones de onda no lineales en dimensión dos. Se aplica un nuevo enfoque topológico para probar la existencia de al menos dos soluciones clásicas no negativas. Los argumentos se basan en un resultado teórico reciente.

    Abstract We study a class of initial value problems for two-dimensional nonlinear wave equations. A new topological approach is applied to prove the existence of at least two nonnegative classical solutions. The arguments are based upon a recent theoretical result.
