POSITIVE SOLUTIONS FOR A CLASS OF SINGULAR SECOND ORDER TWO POINT BOUNDARY
VALUE PROBLEMS
Yan Sun (P. R. China)
|
Abstract: By applying upper and lower solution method, this paper deals with the existence of positive solutions for a class of singular boundary value problems. Sufficient conditions are obtained that guarantee the existence of positive solutions. The interesting point is that the nonlinear term f is involved with the first-order derivative explicitly. |
Keywords and phrases: existence, fixed point, upper and lower solutions, positive solution. |
