Diagonally Implicit 2-Point Block Backward Differentiation Formula With Two Off-Step Points For Solving Stiff Initial Value Problems

Hamisu Musa^*, Alhassan Buhari, Naghmeh Abasi

A diagonally implicit form of the 2-point block backward differentiation formula (BDF) with two off-step points is developed for solving stiff initial value problems. The method is derived by introducing a lower triangular matrix in the coefficient matrix of the existing 2-point block BDF method with off-step points for solving stiff ordinary diffe...

An Extended 2-point Super Class of Block Backward Differentiation Formula with off-step Points for Solving Stiff Initial Value Problems

Hamisu Musa^*, Ahmad Abubakar Umar

In this paper, we considered an extended 2-point Super class of block backward differentiation formula for solving stiff initial value problems (IVPs) and introduced two off-step points in it. The method produces two solution values together with two off-step points simultaneously at each iteration. The varying free parameter ρ is chosen in the int...
