Exact Airy-function evaluation of the Gauss-Bonnet mini-superspace path integral plus Picard-Lefschetz resolution of lapse degeneracies via complex (G ħ) deformation that alters the KSW condition.
Quadratic curvature gravity on Einstein manifolds decouples into massless and non-Fierz-Pauli massive gravity sectors, enabling observational constraints on its parameters with noted tension for the Weyl term.
