View source for Linear integral equation

{{TEX|done}}
An integral equation in which the unknown function $\phi(s)$ occurs in a linear fashion:

$$A(x)\phi(x)+\int\limits_DK(x,s)\phi(s)ds=f(x),\quad x\in D.$$

Here $A$, $K$, $f$ are given functions, $D$ is a domain of the Euclidean space, $k$ and $s$ are points of the space, and $ds$ is the volume element. For more details see [[Integral equation|Integral equation]].
