The first part of this paper considers the effect on the solution of the difference equations from the general self-adjoint elliptic second order partial differential equation of a periodicity condition in the x-direction. There are different effects according to whether n, the number of mesh lengths in this direction, is odd or even, but for Laplace’s equation the asymptotic rates of Cited by: ITERATIVE METHODS FOR SOLVING PARTIAL DIFFERENCE EQUATIONS OF ELLIPTIC TYPE BY DAVID YOUNGO 1.

But the method is not recommend to use for large size problems since the step size should be small enough (in the size of h2 even for the linear problem) and thus it takes large iteration steps to converge to the.

We study iterative methods for solving linear systems arising from two-cyclic discretizations of non-self-adjoint two-dimensional elliptic partial differential equations.

The methods consist of applying one step of cyclic reduction, resulting in a “reduced system” of half the order of the original discrete problem, combined with a. Differential equations are called partial differential equations (pde) or or-dinary differential equations (ode) according to whether or not they contain partial derivatives.

The order of a differential equation is the highest order derivative occurring.

This method was introduced by engineers in the late 50’s and early 60’s for the numerical solution of partial differential equations in structural engineering (elasticity equations, plate equations, and .This means elliptic equations are well suited to describe equilibrium states, where any discontinuities have already been smoothed out.

For instance, we can obtain Laplace's equation from the heat equation u t = Δ u {\displaystyle u_{t}=\Delta u} by setting u t = 0 {\displaystyle u_{t}=0}.
