Optimal operator preconditioning for Galerkin boundary element methods on 3-dimensional screens
We consider first-kind weakly singular and hypersingular boundary integral operators for the Laplacian on screens in R3 and their Galerkin discretization by means of low-order piecewise polynomial boundary elements. For the resulting linear systems of equations we propose novel Calder´on-type precon...
