Gravitational constrained instantons

Year: 2021

Type: article

Abstract: The authors find constrained instantons -- configurations that extremize the action subject to a constraint -- in Einstein gravity with and without a cosmological constant. Such instantons are expected to contribute to non-perturbative processes in quantum gravity. With negative cosmological constant, these configurations describe wormholes connecting two asymptotic regions.
