Tame Complexity of Effective Field Theories in the Quantum Gravity Landscape
Thomas W. Grimm, David Prieto, Mick van Vliet
Effective field theories consistent with quantum gravity obey surprising finiteness constraints, appearing in several distinct but interconnected forms. In this work we develop a f…
