On a Nonlocal Boundary-Value Problem for a Nonlinear Fractional Differential Equation with the Bi-Ordinal Hilfer Derivative
摘要
We consider a boundary-value problem with a nonlocal integral condition for a nonlinear fractional differential equation with a generalized (bi-ordinal) composite Hilfer derivative. The notion of a bi-ordinal Hilfer derivative is based on the interpolation concept using the Caputo and Riemann–Liouville derivatives of different orders. We discuss the existence, uniqueness, and stability of the problem solution.
