The conditioning of boundary element equations on locally refined meshes and preconditioning by diagonal scaling
Consider a boundary integral operator on a bounded, d-dimensional surface in ℝd+1. Suppose that the operator is a pseudodifferential operator of order 2ℳ, ℳ ∈ ℝ, and that the associated bilinear form is symmetric and positive-definite. (The surf
