Interval oscillation criteria for a forced second order nonlinear ordinary differential equations with oscillatory potential

New oscillation criteria established in the paper for a forced second order nonlinear equation with oscillatory potential (p(t)y ′(t)) ′+q(t)f(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,∞), rather...
