Sufficient conditions for the oscillation of forced super-linear second order differential equations with oscillatory potential. (English) Zbl 0891.34038

Summary: In the case of oscillatory potentials, we give sufficient conditions for the oscillation of the forced super-linear equation \[ x''(t)+a(t)|x(t)|^{\nu}\text{ sgn } x(t)=g(t). \] This answers a question raised by J. S. W. Wong [SIAM J. Math. Anal. 19, No. 3, 667-675 (1988; Zbl 0655.34023)].
