Lower a posteriori error estimates on anisotropic meshes
Natalia Kopteva
Lower a posteriori error bounds obtained using the standard bubble function approach are reviewed in the context of anisotropic meshes. A numerical example is given that clearly de…

Error analysis for a fractional-derivative parabolic problem on quasi-graded meshes using barrier functions
Natalia Kopteva, Xiangyun Meng
An initial-boundary value problem with a Caputo time derivative of fractional order is considered, solutions of which typically exhibit a singular behaviour at an initi…
