Euler quadrature rule for a function with a boundary layer component on a picewise uniform mesh
A. I. Zadorin, N. A. Zadorin Omsk Branch of Sobolev Institute of Mathematics, Siberian Branch of the Russian Academy of Sciences
Abstract:
Euler and Gregory quadrature rules for a function with a boundary layer component are investigated. The integrand corresponds to a solution of a singular perturbed problem. It is proved that Euler and Gregory quadrature rules on a mesh, dence in a boundary layer, have a fourth order of an accuracy uniformly in a boundary layer growth of the integrand. Results of numerical experiments are discussed.
Keywords:
function, boundary layer, Euler quadrature formula, piecewise uniform mesh, uniform accuracy.
