Planck Scale Cosmology and Asymptotic Safety in Resummed Quantum Gravity
B. F. L. Ward
In Weinberg's asymptotic safety approach, a finite dimensional critical surface for a UV stable fixed point generates a theory of quantum gravity with a finite number of physical p…
Planck Scale Cosmology and Resummed Quantum Gravity
B. F. L. Ward
We show that, by using amplitude-based resummation techniques for Feynman's formulation of Einstein's theory, we get quantum field theoretic 'first principles' predictions for the…
Towards Exact Quantum Loop Results in the Theory of General Relativity: Status and Update
B. F. L. Ward
We present the status and update of a new approach to quantum general relativity as formulated by Feynman from the Einstein-Hilbert action wherein amplitude-based resummation techn…
Planck Scale Cosmology in Resummed Quantum Gravity
B. F. L. Ward
We show that, by using resummation techniques based on the extension of the methods of Yennie, Frautschi and Suura to Feynman's formulation of Einstein's theory, we get quantum fie…
