The oscillation and strong oscillation of the systems of a class of impulsive delay parabolic equations with quasilinear diffusion coefficient were studied. By using the oscillatory definition, Green's formula and Newmann boundary condition, the oscillatory problem of solution to the systems of impulsive delay parabolic equations was reduced to the nonexistence of position solution of impulsive delay differential inequality, and some sufficient conditions were obtained for the oscillation and strong oscillation of all solutions of such systems through the definition of eventual position soluti...
