【Abstract】 The oscillatory problems of solutions for a class of nonlinear delay hyperbolic distributed parameter systems were studied. By using an integral averaging method, the generalized Riccati transformation and the H(t,s)k(s) type function, some new sufficient criteria were established for oscillation of all solutions of the systems under the third boundary value condition. The obtained results fully show that the oscillation is caused by delay and its effectiveness is illustrated by an example.更多还原
