On a Calderón preconditioner for the symmetric formulation of the electroencephalography forward problem without barycentric refinements
Viviana Giunzioni, John E. Ortiz G., Adrien Merlini +2
We present a Calderón preconditioning scheme for the symmetric formulation of the forward electroencephalographic (EEG) problem that cures both the dense discretization and the hig…
A New Refinement-Free Preconditioner for the Symmetric Formulation in Electroencephalography
Viviana Giunzioni, John E. Ortiz G., Adrien Merlini +2
Widely employed for the accurate solution of the electroencephalography forward problem, the symmetric formulation gives rise to a first kind, ill-conditioned operator ill-suited f…
On the Fast Direct Solution of a Preconditioned Electromagnetic Integral Equation
Davide Consoli, Clément Henry, Alexandre Dély +6
This work presents a fast direct solver strategy for electromagnetic integral equations in the high-frequency regime. The new scheme relies on a suitably preconditioned combined fi…
