摘要
采用Riemann-Liouville分数阶导数,研究了半正的分数阶微分方程(n-1,1)-型积分边值问题,获得了参数λ的一个区间,使得λ落在这个区间的时候,该半正的分数阶微分方程边值问题有多个正解.
In this paper,we consider the(n-1,1)-type integral boundary value problem of nonlinear fractional differential equation D0+^α+u(t)+λf(t,u(t))=0,0t1 U^((j))(0)=0≤j≤n-2 () whereλ,μis a parameter and 0μa,a∈(n-1,n) is a real number and n≥3,D0+^αis the Riemann-Liouville's fractional derivative,and / is continuous and semipositone.We derive an interval of A such that any A lying in this interval,the semipositone boundary value problem has multiple positive solutions.
