摘要
研究了具变号非线性项p-Laplace算子分数阶微分方程正解的存在性.利用双锥上的不动点定理,得到了问题两个正解的存在性的充分条件.推广和改进了现有文献的结论.还举例说明了所得结果的可应用性.
The existence of positive solutions for fractional differential equations involving the p-Laplacian operator with sign changing nonlinearities was investigated.By using the fixed point theorem in double cones,sufficient condition for the existence of two positive solutions to the problem are obtained.The known result is generalized and improved.The applicability of the obtained results is finally proved by examples.
