摘要:This paper is concerned with the existence and uniqueness of solutions for impulsive nonlinear differential equations of fractional order α ∈ ( 1 , 2 ] with closed boundary conditions. By applying some standard fixed point theorems, we obtain the sufficient conditions for the existence and uniqueness of solutions of the problem at hand. An illustrative example is presented.
