Abstract:

This paper investigates a kind of fourth order superlinear singular boundary value problem, which contains a second derivative item. The authors obtain the  existence   and some properties of the solutions. Lastly, a necessary and sufficient condition for the existence of C2[0,1] positive solutions as well as C3[0,1] positive solutions is given for the problems which do not contain derivative items.

Key words: Fourth order differential equation, Singular boundary value problem,  Superlinearity, Fixed point, Positive solution
