Edmen-Fowler type equation of second order; oscillatory and nonoscillatory solutions; oscillatory and nonoscillatory equations
Oscillation and nonoscillation criteria are established for the equation $$u''+p(t)|u|^{\alpha}|u'|^{1-\alpha}\operatorname{sgn} u=0,$$ where $\alpha\in ]0,1]$, and $p:[0,+\infty[\to [0,+\infty[$ is a locally summable function.
