Abstract

We derive fifth-order convergent method in time for the initial value problemWhen applied to test equation y′=−λ y, λ>0, it gives yn+1=Ψ(z)yn, where Ψ(z) does not satisfy the condition for A-stability but Ψ(z)→0 as z→∞. To develop this method we use a higher order average approximation which is based on osculatory cubic polynomial interpolation coupled with fourth-order backward Taylor's series approximation. We also test this method on Burgers’ equation. Computed solutions are quite encouraging and does not give oscillations when inconsistencies are present in terms of initial and boundary conditions.
