DESCRIPTION:David Stone\nWe investigate the trace anomaly of a quantum fie
 ld theory on a curved background with (background) spacetime-dependent cou
 plings in six dimensions. The spacetime dependence of the couplings allows
  one to study the trace anomaly away from conformal fixed points. In parti
 cular the possibility of a strong a-theorem in six dimensions in multi-fla
 vor φ^3 theory is considered. Contrary to the case in two and four dimens
 ions\, we find that in perturbation theory the relevant quantity \\tilde{a
 }\, the natural extension of the infamous a-quantity away from fixed point
 s\, increases monotonically along flows away from the trivial fixed point.
  We also present results from a related theory in six dimensions where \\t
 ilde{a} decreases away from UV fixed points. These results suggest that so
 me new intuition about the a-theorem is in order.
