 A note on approximation of solutions of a K-positive definite operator equations Bull. Korean Math. Soc. 2001 Vol. 38, No. 2, 231-236 M. O. Osilike and A. Udomene University of Nigeria, University of Nigeria Abstract : In this note we construct a sequence of Picard iterates suitable for the approximation of solutions of $K$-positive definite operator equations in arbitrary real Banach spaces. Explicit error estimate is obtained and convergence is shown to be as fast as a geometric progression. Keywords : K-positive definite operators, Picard iteration MSC numbers : 47A50 Downloads: Full-text PDF
