摘要：In this paper we study the chebyshev and interpolation error for a real valued generalized biaxisymmetric Potential (GBASP) which is regular in the open hyper sphere about the origin. The lower (p, q) order and lower generalized (p, q) – type have been characterized in terms of these approximation errors. Ethiopian Journal of Education and Science Vol. 2 (1) 2006: pp. 129-141
