Co-isotropic and Legendre - Lagrangian submanifolds and conformal Jacobi morphisms

Abstract

The notion of a co-isotropic and Legendre-Lagrangian submanifold of a Jacobi manifold is given. A characterization of conformal Jacobi morphisms and conformal Jacobi infinitesimal transformations is obtained as co-isotropic and Legendre-Lagrangian submanifolds of Jacobi manifolds.
