Ultraviolet Finiteness or Asymptotic Safety in Higher Derivative Gravitational Theories
We present and discuss well known conditions for ultraviolet finiteness and asymptotic safety. The requirements for complete absence of ultraviolet divergences in quantum field theories and existence of a non-trivial fixed point for renormalization group flow in the ultraviolet regime are compared b...
