【Abstract】 The conditions for existence of positive solutions of difference equations with continuous variable are given by use of oscllation results for difference equations with discrete variable.Furthermore,sufficient conditions for oscillation of difference equations with variable coefficients are established by the aid of Lebesgue contral convergence theorem.更多还原
