Given the matter density [rho](x, t), the dynamics of the gravitational field is being determined through Poisson's equation
[[nabla].sup.2][phi] = ([kappa]/2)[rho].
To make the used plasma system equations ((1a), (1b), and (1c)) self-consistent, Poisson's equation
is proceeded as
Thus, the problem of solving (15) is reduced to the problem of solving the following Poisson's equation
We can write the divergence of Equation 4 as a form of Poisson's equation
is changed into Laplace's equation [[nabla.sup.2][phi] = 0.
In particular, applying normalized systems and Almansi expansions, Karachik studied solutions of some partial equations and some boundary value problems for Poisson's Equation
This calculation leads to solving the Poisson's equation
, which needs models of the source (brain activities) and the head.
Finite difference approximation of Poisson's equation
in polar irregular mesh is defined as

This equation is shown to lead to Poisson's equation
for a newtonian gravitational potential in the next section.
