Summary<br />

•While strict perturb<strong>at</strong>ion theory is meaningless, weak coupling methods<br />

(involving resumm<strong>at</strong>ions) provide an accur<strong>at</strong>e description of the QGP for<br />

• The functional <strong>renormaliz<strong>at</strong>ion</strong> <strong>group</strong> confirms results obtained with various<br />

resumm<strong>at</strong>ions (<strong>at</strong> least in scalar case)
