【Abstract】 In this paper we study the oscillation of the solutions of non-linear equation where f, f(x) g(x), are continuous and the solution of Cauchy problem of (E) is unique. We obtain a series of necessary and sufficient conditions for the oscillation of system (E). The work of [2], [4] is generalized and the results of [5] are improved.更多还原
