Positive solutions for Dirichlet problems of singular nonlinear fractional differential equations. (English) Zbl 1206.34009
Consider the existence of a positive solution for the singular fractional boundary value problem
$D^\alpha u(t)+ f(t,u(t),D^\mu u(t))=0,\,u(0)=u(1)=0,$
where $$1<\alpha<2$$, $$\mu>0$$ with $$\alpha-\mu\geq 1,$$ $$D^\alpha$$ is the standard Riemann-Liouville fractional derivative, the function $$f$$ is positive, satisfies the Carathéodory conditions on $$[0,1]\times (0,\infty)\times {\mathbb R}$$ and $$f(t,x,y)$$ is singular at $$x=0$$.
The proofs are based on regularization and sequential techniques and the results are obtained by means of fixed point theorem of cone compression type due to [M. A. Krasnosel’skij, Positive solutions of operator equations. Groningen: The Netherlands: P.Noordhoff Ltd. (1964; Zbl 0121.10604)].
