Some Limit-point and Limit-circle Results for Second Order Emden–Fowler Equations
Miroslav Bartusbreveek, John R. Graef · Applicable Analysis · 2004
The authors study the Emden–Fowler differential equation where a(t)>0, r(t) > 0 , and λ ≠ 1 is positive. They consider both the case and the case and obtain some sufficient conditions for (E) to be of the nonlinear limit-circle type, sufficient conditions for it to be of the nonlinear limit-point type, and some necessary and sufficient conditions for equation (E) to be of the nonlinear limit-circle type.
