摘要
利用锥拉伸与压缩不动点定理,给出了四阶微分方程奇异边值问题C2[0,1]和C3[0,1]正解的存在性.
The existence of two C^2[0,1] positive solutions as well as C^3[0,1] positive solutions is established for a singular boundary value problems of fourth order differential equations by using the fixed point theorem of cone expansion and cone compression of norm type.
