A new mathematical formulation for a phase change problem with a memory flux [PDF]

open access: yes, 2018
A mathematical formulation for a one-phase change problem in a form of Stefan problem with a memory flux is obtained. The hypothesis that the integral of weighted backward fluxes is proportional to the gradient of the temperature is considered. The model

Nonlocal boundary value problem for generalized Hilfer implicit fractional differential equations [PDF]

open access: yesMathematical Methods in the Applied Sciences, 2020
In this paper, we derive the equivalent fractional integral equation to the nonlinear implicit fractional differential equations involving Ψ‐Hilfer fractional derivative subject to nonlocal fractional integral boundary conditions. The existence of a solution, Ulam–Hyers, and Ulam–Hyers–Rassias stability have been acquired by means of an equivalent ...
