Numerical Analysis
1. A BACKWARD DIFFERENTIATION FORMULA FOR THIRD-ORDER INITIAL OR BOUNDARY VALUES PROBLEMS USING COLLOCATION METHOD

ABD'GAFAR TUNDE TIAMIYU; Abosede Temilade COLE; KHADEEJAH JAMES AUDU

Articles in Press, Accepted Manuscript, Available Online from 19 September 2021

Abstract
  We propose a new self-starting sixth-order hybrid block linear multistep method using backward differentiation formula for direct solution of third-order differential equations with either initial conditions or boundary conditions. The method used collocation and interpolation techniques with three off-step ...  Read More

Numerical Analysis
2. Convergence of Triple Accelerated Over-Relaxation (TAOR) Method for M-Matrix Linear Systems

KHADEEJAH JAMES AUDU; Yusuph Amuda Yahaya; Rufus Kayode Adeboye; Usman Yusuf Abubakar

Articles in Press, Accepted Manuscript, Available Online from 19 September 2021

Abstract
  In this paper, we propose some necessary conditions for convergence of Triple Accelerated Over-Relaxation (TAOR) method with respect to $M-$ coefficient matrices. The theoretical approach for the proofs is analyzed through some standard procedures in the literature. Some numerical experiments are performed ...  Read More
