✦ Synopsis

Dimensional reduction of finite temperature quantum field theories can be improved with the help of continous renormalisation group steps. The method is applied to the integration of the lowest nonstatic (n=\1) modes of the finite temperature 8 4 -theory. A second, physically important application is the integration of the Debye-screened A 0 (x) static scalar potential in the gauged SU(2) Higgs model.

In Rosen's "bimetric" theory of gravity the (local) speed of gravitational radiation u. is determined by the combined effects of cosmological boundary values and nearby concentrations of matter. It is possible for v. to be less than the speed of light. I show here that emission of gravitational radi
