Limit-point/limit-circle results for superlinear damped equations (Q2319105)

Summary: The authors study the nonlinear limit-point and limit-circle properties for second-order nonlinear damped differential equations of the form \((a(t) | y' |^{p - 1} y')' + b(t) | y' |^{q - 1} y' + r(t) | y |^{\lambda - 1} y = 0\), where \(0 < q \leq p \leq \lambda\), \(a(t) > 0\), and \(r(t) > 0\). Examples to illustrate the main results are included.
