DOI: 10.1016/j.geomphys.2020.103904
Abstract: Abstract We study linear Jacobi structures on vector spaces and their non-degenerate version, the linear contact structures. We touch several aspects, like transitivity, Poissonization, coisotropy, product structures, transversals. We consider the linear version of contact… read more here.
