| Abstract: | The existence of solutions for the boundary value problem of a class of the fractional differential equation -Dβ0+u(t)=f(t,u(t)), 0≤t≤1, u(0)=u'(1)=θ in Banach spaces E is discussed, where 1<β≤2, Dβ0+ is the standard Riemann - Liouville fractional derivative, f:[0,1]×E→E is continuous.The existence of the solution of the boundary value problem is obtained by using the fixed point theorem of condensed mapping under the condition of weak growth of nonlinear terms, by using the estimation technique of noncompactness measure. |
