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…
A Calderon Regularized Symmetric Formulation for the Electroencephalography Forward Problem
John E. Ortiz G., Axelle Pillain, Lyes Rahmouni +1
The symmetric formulation of the electroencephalography (EEG) forward problem is a well-known and widespread equation thanks to the high level of accuracy that it delivers. However…
On the Hierarchical Preconditioning of the PMCHWT Integral Equation on Simply and Multiply Connected Geometries
J. E. Ortiz Guzman, S. B. Adrian, R. Mitharwal +4
We present a hierarchical basis preconditioning strategy for the Poggio-Miller-Chang-Harrington-Wu-Tsai (PMCHWT) integral equation considering both simply and multiply connected ge…
