Title: Generalized quasilinearization method for a second order three point boundary-value problem with nonlinear boundary conditions Authors: Bashir Ahmad (King Abdulaziz Univ. Saudi Arabia) Rahmat Ali Khan (Quaid-i-Azam Univ., Pakistan) Paul W. Eloe (Univ. of Dayton, OH, USA) Abstract: The generalized quasilinearization technique is applied to obtain a monotone sequence of iterates converging uniformly and quadratically to a solution of three point boundary value problem for second order differential equations with nonlinear boundary conditions. Also, we improve the convergence of the sequence of iterates by establishing a convergence of order $k$. Submitted March 14, 2002. Published October 22, 2002.
