Interval oscillation criteria for second-order damped differential equations with mixed nonlinearities (Q310686)

This paper deals with the second order differential equation of the form \[ \left( r(t)(x'(t))^{\gamma }\right)'+p(t)(x'(t))^{\gamma }+\sum \limits_{i=0}^{n}q_{i}(t)\left | x(g_{i}(t))\right | ^{\alpha _{i}}\mathrm{sgn }x(g_{i}(t))=e(t). \] Using the Riccati transformation technique and inequalities, some interval oscillation criteria are established.
