Abstract:This article is a improvement on author's early work (Acta Mathematica Scientia, Vol.30 No.2 Ser.A 2010). In this article, there are two new contributions: 1) The restrictive conditions on approximation domain boundary is improved essentially. 2) The Fejér points is extended by perturbed Fejér points with stable order of approximation.
Keywords:Harmonic interpolation approximation  perturbed Fejé  r points  stable order of approximate  boundary restriction condition
