Conforming and non-conforming virtual element methods for the biharmonic Steklov eigenvalue problem with minimum regularity
Dibyendu Adak, Daniele Boffi, Francesca Gardini +2
In this work, we analyze the conforming and -non-conforming Virtual Element Method for a fourth-order Steklov eigenvalue problem on a generally shaped, possibly nonconvex, pol…

Auxiliary Gradient-Flow Solvers for Generalized Newtonian Models
Stefano Zampini, Daniele Boffi, Gurt Dovletov +1
We introduce an auxiliary gradient-flow framework for variational problems with generalized Newtonian structure governed by an N-function. The key idea is to replace the nonlinear…

Multigrid Preconditioning for FD-DLM Method in Elliptic Interface Problems
Najwa Alshehri, Daniele Boffi, Chayapol Chaoveeraprasit
We investigate the performance of multigrid preconditioners for solving linear systems arising from finite element discretizations of elliptic interface problems using the Fictitio…
