چکیده
This paper concerns the oscillation of solutions to the differential equation ` r(t)x′(t) ́′ + p(t)x′(t) + q(t)g(x(t)) = 0, where xg(x) > 0 for all x 6= 0, r(t) > 0 for t ≥ t0 > 0. No sign conditions are imposed on p(t) and q(t). Our results solve the open problem posed by Rogovchenko [27], complement the results in Sun [29], and improve a number of existing oscillation criteria. Our main results are illustrated with examples.

Oscillation of Second Order Nonlinear Differential Equations with a Damping Term
A class of second-order nonlinear differential equations with a damping term is investigated in this paper. By using the Riccati transformation technique and general weight functions, we obtain some new sufficient conditions for the oscillation of the equation. Our results improve and extend some known results. Two examples are given to illustrate the main results.
