Universal Gibbons-Hawking-York term for theories with curvature, torsion and non-metricity
Universal Gibbons-Hawking-York term for theories with curvature, torsion and non-metricity
Motivated by establishing holographic renormalization for gravitational theories with non-metricity and torsion, we present a new and efficient general method for calculating Gibbons-Hawking-York (GHY) terms. Our method consists of linearizing any nonlinearity in curvature, torsion or non-metricity by introducing suitable Lagrange multipliers. Moreover, we use a split formalism for differential …
