Some examples are given to demonstrate the validity of our main result. Our results generalize classical and newer results in the literature. As an application, we solve the initial value problem of damped harmonic oscillator and a nonlinear fractional differential equation satisfying periodic boundary conditions, which demonstrates the importance of our contraction and provides motivation for such investigations.</p> </div> </div> </div> 2019-11-15T17:27:33+00:00 Copyright (c) 2019 Armenian Journal of Mathematics
