Numerical solution of integral equations in the density problems

In this paper density problems are restricted to the current and the heat conduction. Analysis of the current density leads to system integral equations of the Fredholm type [4-5]. That problem in timeprovides to the mathematical model determined by the system of integro-differenti al equations [2-3] and it is extended for few conductors. The functions density for heat conduction problems are determined by Volterra-Fredholm integral equations. Presented theory is illustrated fay computational experiments.
