Simpson Type Estimations for Convex Functions via Quantum Calculus

Annals of Mathematics and Physics
We first establish a new identity including quantum integrals and quantum numbers via q -differentiable functions. After that, with the help of this equality, a Simpson-type inequality for functions whose quantum derivatives in modulus are convex is ...

Monotone iterative technique for a sequential delta-Caputo fractional differential equations with nonlinear boundary conditions

Studia Universitatis Babeş-Bolyai. Mathematica
. In this article, we discuss the existence of extremal solutions for a class of nonlinear sequential δ–Caputo fractional differential equations involving nonlinear boundary conditions. Our results are founded on advanced functional analysis methods.

On the nonlinear sequential ψ-Hilfer fractional differential equations

, 2020
In this paper, we discuss the existence and uniqueness of solutions for a class of nonlinear sequential ψ-Hilfer fractional differential equations. This investigation is carried out by means of Schaefer’s fixed point theorem and modified version of ...

Existence, regularity and representation of solutions of time fractional diffusion equations

Advances in Differential Equations, 2016
Using regularized resolvent families, we investigate the solvability of the fractional order inhomogeneous Cauchy problem Dt u(t) = Au(t) + f(t), t > 0, 0 < α ≤ 1, where Dt is the Caputo fractional derivative of order α, A a closed linear operator on ...
