Optimal rearrangement problem and normalized obstacle problem in the fractional setting

open access: yesAdvances in Nonlinear Analysis, 2020
We consider an optimal rearrangement minimization problem involving the fractional Laplace operator (–Δ)s, 0 < s < 1, and the Gagliardo seminorm |u|s. We prove the existence of the unique minimizer, analyze its properties as well as derive the non-local ...

Equivalence between a time-fractional and an integer-order gradient flow: The memory effect reflected in the energy

open access: yesAdvances in Nonlinear Analysis, 2022
Time-fractional partial differential equations are nonlocal-in-time and show an innate memory effect. Previously, examples like the time-fractional Cahn-Hilliard and Fokker-Planck equations have been studied.

A posteriori error estimates based on superconvergence of FEM for fractional evolution equations

open access: yesOpen Mathematics, 2021
In this paper, we consider an approximation scheme for fractional evolution equation with variable coefficient. The space derivative is approximated by triangular finite element and the time fractional derivative is evaluated by the L1 approximation. The
