	abstract = {<div>We study the thermoelectric transport properties in the three-dimensional Anderson model of localization near the metal-insulator transition (MIT). In particular, we investigate the dependence of the thermoelectric power <em>S</em>, the thermal conductivity <em>K</em>, and the Lorenz number <em>L</em>0 on temperature <em>T</em>. We first calculate the <em>T</em> dependence of the chemical potential μ from the number density <em>n</em> of electrons at the MIT using an averaged density of states obtained by diagonalization. Without any additional approximation, we determine from the behavior of <em>S</em>, <em>K</em> and <em>L</em>0 at low <em>T</em> as the MIT is approached. We find that the d.c. conductivity and <em>K</em> decrease to zero at the MIT as <em>T</em> -\&gt; 0 and show that <em>S</em> does not diverge. Both <em>S</em> and <em>L</em>0 become temperature independent at the MIT and depend only on the critical behavior of the conductivity.</div>},
