Basic theory on a class of initial value problem of some fractional differential equation involving Riemann-Liouville differential operators is discussed by employing the classical approach from the work of Lakshmikantham ...

We established the existence of a positive solution of nonlinear fractional differential equations pound (D) [x(t)-x(0)] = f(t, x(t)), t. is an element of (0, b], with finite delay x (t) = omega (t), t is an element of ...

The main purpose of this manuscript is to prove the existence of solutions for delay fractional order differential equations (FDE) at the neighborhood of its equilibrium point. After we convert the delay FDE into linear ...
