We present the notion of orthogonal F-metric spaces and prove some fixed and periodic point theorems for orthogonal ⊥Ω-contraction. We give a nontrivial example to prove the validity of our result. Finally, as application, we prove the existence and uniqueness of the solution of a nonlinear fractional differential equation.
