Impulsive partial differential systems can be successfully used for mathematical simulation in mechanics,theory physics,chemistry,population dynamics,biotechnology,optimal control and economics, etc.The oscillation theory is the one of the important branches of qualitative theory of impulsive partial differential systems.Therefore,it is of great theoretical and practical value to research the oscillation of partial functional differential equations.In this paper,the(strong)oscillation problems for a class of quasilinear hyperbolic systems based...
