Estimation of quadrature errors in layer potential evaluation using quadrature by expansion
In boundary integral methods it is often necessary to evaluate layer potentials on or close to the boundary, where the underlying integral is difficult to evaluate numerically. Quadrature by expansion (QBX) is a new method for dealing with such integrals, and it is based on forming a local expansion of the layer potential close to the boundary. In doing so, one introduces a new quadrature error...
متن کاملQuadrature by expansion: A new method for the evaluation of layer potentials
Integral equation methods for the solution of partial differential equations, when coupled with suitable fast algorithms, yield geometrically flexible, asymptotically optimal and well-conditioned schemes in either interior or exterior domains. The practical application of these methods, however, requires the accurate evaluation of boundary integrals with singular, weakly singular or nearly sing...
متن کاملUbiquitous evaluation of layer potentials using Quadrature by Kernel-Independent Expansion
We introduce a quadrature scheme—QBKIX—for the ubiquitous highorder accurate evaluation of singular layer potentials associated with general elliptic PDEs, i.e., a scheme that yields high accuracy at all distances to the domain boundary as well as on the boundary itself. Relying solely on point evaluations of the underlying kernel, our scheme is essentially PDE-independent; in particular, no an...
متن کاملAsymptotic estimation of Gaussian quadrature error for a nonsingular integral in potential theory
This paper considers the n-point Gauss-Jacobi approximation of nonsingular integrals of the form ∫ 1 −1 μ(t)φ(t) log(z− t) dt, with Jacobi weight μ and polynomial φ, and derives an estimate for the quadrature error that is asymptotic as n → ∞. The approach follows that previously described by Donaldson and Elliott. A numerical example illustrating the accuracy of the asymptotic estimate is pres...
متن کاملAn Error Expansion for Gauss–Turán Quadrature with Chebyshev Weight Function
Our aim in this paper is to obtain an expansion for the error in the Gauss-Turán quadrature formula for approximating ∫ 1 −1 w(t)f(t) dt in the case when the function f is analytic in some region of the complex plane containing the interval [−1, 1] in its interior, and the remainder term is presented in the form of a contour integral over the confocal ellipses. In the case w(t) = 1/ √ 1 − t2 we...
