%0 Journal Article %T On quasi-Jacobi and Jacobi-quasi bialgebroids %A J. M. Nunes da Costa %A F. Petalidou %J Mathematics %D 2006 %I arXiv %R 10.1007/s11005-007-0151-5 %X We study quasi-Jacobi and Jacobi-quasi bialgebroids and their relationships with twisted Jacobi and quasi Jacobi manifolds. We show that we can construct quasi-Lie bialgebroids from quasi-Jacobi bialgebroids, and conversely, and also that the structures induced on their base manifolds are related via a quasi Poissonization. %U http://arxiv.org/abs/math/0612146v2
