² is the Laplace operator, λ is a constant, and f is an arbitrary function of position (known as the "source function".) The screenedPoissonequation occurs frequently in physics, including Yukawa's theory of mesons and electric field screening in plasmas.
The screenedPoissonequation can be solved for general f using the method of Green's functions.
The screened 1/r function is often encountered in physics as a screened Coulomb potential, also called a "Yukawa potential".
In mathematics, Poisson'sequation is a partial differential equation with broad utility in electrostatics, mechanical engineering and theoretical physics.
The Poissonequation may be solved using a Green's function; a general exposition of the Green's function for the Poissonequation is given in the article on the screenedPoissonequation.
One of the principle cornerstones of electrostatics is the posing and solving of problems that are described by the Poissonequation.
The screenedPoissonequation is the following partial differential equation:
² is the Laplace operator, λ is a constant, and f is an arbitrary function of position (known as the "source function.) The screenedPoissonequation occurs frequently in physics, including Yukawa's theory of mesons and electric field screening in plasmas.
When λ is zero, the equation reduces to Poisson'sequation.

A different form of the equation is sometimes used for certain types of materials, e.g.
As we shall the solution for intermediate values of λ behaves as a superposition of screened (or damped) 1/ r functions with λ behaving as the strength of the

A linear equation in algebra is an equation which is constructed by equating two linear functions.
A linear equation is an equation containing only functions that are linear in the variables of interest: put more simply, terms such as x 2 are not allowed.

Screened Iterative Solution of the Poisson Equation(Site not responding. Last check: 2007-10-21)
The Coulomb potential is expressed as a convolution of a screenedYukawa potential with a generalized source, which is a linear combination of charge density and the Coulomb potential itself.
The resulting integral equation is solved self-consistently using the Broyden algorithm, which typically converges in 20 iterations.
Convergence is such that only a small cluster around each atom type is needed for high accuracy.
