Metric-affine cosmological models and the inverse problem of the calculus of variations. Part 1: variational bootstrapping – the method

Abstract The method of variational completion allows one to transform an (in principle, arbitrary) system of partial differential equations – based on an intuitive “educated guess” – into the Euler–Lagrange one attached to a Lagrangian, by adding a canonical correction term. Here, we extend this tec...
