Limit-point/limit-circle results for equations with damping. (English) Zbl 1260.34053
Summary: The authors study the nonlinear limit-point and limit-circle properties for the second-order nonlinear damped differential equation $$(a(t)|y'|^{p-1}y')' + b(t)|y'|^{q-1}y' + r(t)|y|^{\lambda -1}y = 0,$$where $0 < \lambda \leq p \leq q$, $a(t) > 0$, and $r(t) > 0$. Some examples are given to illustrate the main results.
