We prove the existence and uniqueness of solutions for nonlinear integro-differential equations of fractional order q e 1 2 with three-point nonlocal fractional boundary conditions by applying some standard fixed point theorems. 1. Introduction Fractional calculus differentiation and integration of arbitrary order is proved to be an important tool in the modelling of dynamical systems associated with phenomena such as fractal and chaos. In fact this branch of calculus has found its applications in various disciplines of science and engineering such as mechanics electricity chemistry biology economics control theory signal and image processing polymer rheology regular variation in thermodynamics biophysics blood flow phenomena aerodynamics electro-dynamics of complex medium viscoelasticity and damping control theory wave propagation percolation identification and fitting of experimental data 1-4 . Recently differential equations of fractional order have been addressed by several researchers with the sphere of study ranging from the theoretical aspects of existence and uniqueness of solutions to the analytic and numerical methods for finding
