Solvability and optimal controls of non-instantaneous impulsive stochastic fractional differential equation of order q ∈ (1,2)

Stochastics, 2020
In this article, we study the stochastic fractional optimal control problem for a system governed by a class of non-instantaneous impulsive stochastic fractional differential equation in the infinite-dimensional spaces. We utilize the fractional calculus,

Inverse source problems for a space–time fractional differential equation

Inverse Problems in Science and Engineering, 2020
We considered two inverse source problems for a space–time fractional differential equation. Firstly recovery of a space dependent source term is studied, secondly determination of a time dependent source term is considered.

Inverse problem for a multi-term fractional differential equation

Fractional Calculus and Applied Analysis, 2020
Inverse problem for a family of multi-term time fractional differential equation with non-local boundary conditions is studied. The spectral operator of the considered problem is non-self-adjoint and a bi-orthogonal set of functions is used to construct ...

Fractional differential equations and the Schrödinger equation

Applied Mathematics and Computation, 2005
The authors study fractional differential equations associated to the \(\alpha\)-derivative, where such equations appear in many problems. In particular, they obtain a fractional differential equation related to the classical Schrödinger equation by studying Nottale's approach to quantum mechanics via a fractal space-time.

Multivalued fractional differential equations

Applied Mathematics and Computation, 1995
The authors study the Cauchy problem of a multivalued fractional differential equation as a consequent result of the study of Cauchy problem of fractional differential equations in the Banach space \(E\). They prove some theorems and present their existence and some other properties.

On the fractional differential equations

Applied Mathematics and Computation, 1992
The author deals with the semilinear differential equation \(d^ \alpha x(t)/dt^ \alpha=f(t,x(t))\), \(t>0\), where \(\alpha\) is any positive real number. In [Kyungpook Math. J. 28, No. 2, 119-122 (1988; Zbl 0709.34011)] the author has proved the existence, uniqueness, and some properties of the solution of this equation when ...
