POSITIVE SOLUTIONS OF SINGULAR SUBLINEAR EMDEN-FOWLER BOUNDARY-VALUE-PROBLEMS

[摘要] This paper is about the Dirichlet boundary value problem of singular sublinear Emden-Fowler equations. A necessary and sufficient condition for the existence of positive solutions to this problem has been obtained by using the method of lower and upper solutions. The uniqueness of positive solutions has also been discussed. (C) 1994 Academic Press, Inc.
