%X we characterize the \it fucik spectrum (see [7]) of a class selfadjoint operators. our characterization relies on lyapunov-schmidt reduction arguments. we use this characterization to establish the existence of solutions for a semilinear wave equation. this work has been motivated by the authors results in [4] where one dimensional second order ordinary differential equations are studied.
