WebSOLUTIONS OF THE GENERALIZED EMDEN-FOWLER EQUATIONS AND ITS APPLICATION TO ELLIPTIC PROBLEMS KEN-ICHI KAMO Abstract. This paper is concerned with the problem of asymptotic equiva-lence for positive rapidly decaying solutions of a class of second order quasi-linear ordinary di erential equations. WebA sufficient condition is given for the existence of a solution for a generalized Emden–Fowler problem with a free end point. In the special case of the Emden–Fowler equation, this condition is also necessary; and moreover, a monotone iteration scheme holds for the approximation of a positive solution.
