Compatibility of Riemannian structures and Jacobi structures

We give a notion of compatibility between a Riemannian structure and a Jacobi structure. We prove that in case of fundamental examples of Jacobi structures : Poisson structures, contact structures and locally conformally symplectic structures, we get respectively Riemann-Poisson structures in the sense of M. Boucetta, (1∕2)-Kenmotsu structures and locally conformally Kähler structures.
