C-<strong>theorems</strong> in higher dimensions<br />
d=2:<br />
d=4:<br />
and<br />
• in 4 dimensions, have three central charges:<br />
• do any of these obey a similar “c-theorem” under RG flows<br />
-theorem: proposed by Cardy (1988)<br />
• numerous nontrivial examples, eg, perturbative fixed<br />
points (Jack & Osborn), SUSY gauge theories (Anselmi et al)<br />
• holographic field theories with gravity dual<br />
• no completely general proof<br />
• counterexample proposed: Shapere & Tachikawa, 0809.3238
