Supercloseness of linear finite element method on Bakhvalov-type meshes for singularly perturbed convection-diffusion equation in 1D
The authors use a linear finite element method on Bakhvalov-type meshes to solve a singularly perturbed two-point boundary value problem (in one dimension). Thanks to a novel interpolation to the solution, a new supercloseness result is derived and proved.
