【Abstract】 New oscillation criteria established for a second order nonlinear ordinary differential equation with oscillatory potential(r(t)y′(t))′+p(t)y′(t)+Q(t,y(t))=g(t) are different from the most known ones in the sense that they are based on the information only on a sequence of subintervals of[t-0,+∞).更多还原
