摘要: In this paper we investigate the properties of the solutions of a class of second order neutral differential inequalities with distributed type deviating arguments. We apply the properties on the inequalities to obtain some new criteria for all solutions of certain neutral hyperbolic partial functions differential equations to be oscillatory.
