Inverse source problem for time fractional diffusion equation with Mittag-Leffler kernel
Advances in Difference Equations, 2020 In this work, we study the problem to identify an unknown source term for the Atangana–Baleanu fractional derivative. In general, the problem is severely ill-posed in the sense of Hadamard.

A Priori Error Estimates for Approximation of Parabolic Boundary Value Problems [PDF]
SIAM Journal on Numerical Analysis, 1975 The $L^2 $-error estimates are established for the continuous time Faedo–Galerkin approximation to solutions of a linear parabolic initial boundary value problem that has elliptic part of order $2m$. Properties of analytic semigroups are used to obtain these estimates directly from the $L^2 $-estimates for the corresponding steady state elliptic ...

A posteriori error control for a quasi-continuum approximation of a periodic chain [PDF]
, 2013 We consider a one-dimensional periodic atomistic model, for which we formulate and analyse an adaptive variant of a quasicontinuum method. We establish a posteriori error estimators for the energy norm and for the energy, based on a posteriori residual ...
