On the topological character of metric-affine Lovelock Lagrangians in critical dimensions
In this paper we prove that the k-th order metric-affine Lovelock Lagrangian is not a total derivative in the critical dimension n=2k in the presence of non-trivial non-metricity. We use a bottom-up approach, starting with the study of the simplest cases, Einstein-Palatini in two dimensions and Gaus...
