摘要
利用上下解方法与Schauder不动点定理,研究了一类非线性分数阶边值问题解的存在性:{D(0+)^αu(t)=f(t,u(t)),t∈[0,1],u(0)=u(1)=u′(0)=u′(1)=0,其中α∈(3,4],是一实数,D(0+)^α是Riemann-Liouville分数阶导数,推广和改进了已有的结果.
By using the Schauder fixed point theorem and the methods of the upper and lower solution,the existence of solutions for the boundary value problems of a type fractional differential equations is studied:{D_(0+)~αu(t)=f(t,u(t)),t∈ [0,1],u(0)=u(1)=u′(0)=u′(1)=0,whereα∈(3,4],andαis a real number;D0+~α is Riemann-Liouville fractional derivative,and some known results are generalized and improved.
