2026-07-072026-07-07http://salesiana.dossiersoluciones.com/handle/123456789/73555We first recall some basic definitions and facts about Jacobi manifolds, generalized Lie bialgebroids, generalized Courant algebroids and Dirac structures. We establish an one-one correspondence between reducible Dirac structures of the generalized Lie bialgebroid of a Jacobi manifold $(M,Λ,E)$ for which 1 is an admissible function and Jacobi quotient manifolds of $M$. We study Jacobi reductions from the point of view of Dirac structures theory and we present some examples and applications.18 pagesSymplectic GeometryDifferential Geometry53D10, 53D17, 53D20, 58A30text
