Existence and uniqueness of solutions of initial value problems for nonlinear fractional differential equations
Considered are existence and uniqueness of solutions of the following initial value problems \[ D^\alpha x(t)=f(t,D^\beta x(t)),\, 0<t\leq 1;\quad x^{(k)}=n_k,\,k=0,1,\dots,m-1, \] where \(m-1<\alpha<m,\) \(n-1<\beta<n\) \((m,n\in \mathbb{N},\,m-1>n)\), \(D^\alpha\) stands for the Caputo derivative of order \(\alpha\) and \(f\) is a continuous function defined on \([0,1]\times \mathbb{R}\). The proofs are achieved by means of the contraction mapping principle.
