New Criteria for Oscillation of Nonlinear Hyperbolic Equations with Influence of Impulse and Delay
Abstract:The oscillatory properties of a class of impulsive delay hyperbolic partial differential equations with nonlinear diffusion term were considered. By employing first order impulsive delay differential inequalities, some sufficient criteria for the oscillation of all solutions of the equations were obtained under Dirichlet boundary value condition.
