SUMMARY:3D minimal massive gravity: the third way - Paul Townsend (DAMTP)

DESCRIPTION:Two types of source tensor can appear on the right hand side o
 f Einstein's gravitational field equations. One is a stress tensor for mat
 ter. The other (which leads to higher-derivative corrections) is a tensor 
 obtained by variation of some gravitational invariant. But in three spacet
 ime dimensions (3D) there is a ``third way''. Starting with ``Topologicall
 y Massive Gravity'' (TMG) the 3rd way yields ``Minimal  Massive Gravity'' 
 (MMG)\, which resolves the holographic unitarity problem of TMG. Starting 
 with 3D Yang-Mills theory\, the 3rd way  yields a new class of gauge theor
 ies.
