New metric-affine generalizations of gravitational wave geometries Jiménez-Cano, Alejandro In this paper we explore generalizations of metric structures of the gravitational wave type to geometries containing an independent connection. The aim is simply to establish a new category of connections compatible, according to some criteria, to the known metric structures for gravitational waves and, additionally, provide some properties that can be useful for the search of solutions of this kind in different theories. 2020-11-10T12:04:46Z 2020-11-10T12:04:46Z 2020 info:eu-repo/semantics/article Jiménez-Cano, A.
