TY - JOUR AU - Janssen, Bert AU - Jiménez-Cano, Alejandro PY - 2019 UR - http://hdl.handle.net/10481/58217 AB - 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...
