Mixed Hybrid High-Order Methods for Sixth-Order Problems: Fully Non-conforming and -Conforming Discretizations
Arbaz Khan, Ajay Kumar, Harpal Singh
We consider a class of sixth-order elliptic partial differential equations in two and three dimensions subject to simply supported and Cahn--Hilliard-type boundary conditions. Base…

Adaptive Mixed FEM for the Stokes eigenvalue problem
Daniele Boffi, Arbaz Khan
In this paper we discuss the optimal convergence of a standard adaptive scheme based on mixed finite element approximation to the solution of the eigenvalue problem associated with…
