Abstract
In this paper, distribution of zeros of solutions to functional equations in a space of functions of two variables is studied. It will be demonstrated that oscillation properties of functional equations are determined by the spectral radius of a corresponding operator acting in the space of essentially bounded functions. An exact nonoscillation test will be obtained.
