Título: | Twisted Jacobi manifolds, twisted Dirac-Jacobi structures and quasi-Jacobi bialgebroids | Autor: | Costa, J. M. Nunes da Petalidou, F. |
Palavras-chave: | Twisted Jacobi manifold; Twisted Dirac-Jacobi structure; Jacobi bialgebroid; Courant-Jacobi algebroid; Quasi-Jacobi bialgebroid | Data: | 2006 | Editora: | Centro de Matemática da Universidade de Coimbra | Citação: | Pré-Publicações DMUC. 06-19 (2006) | Resumo: | We study twisted Jacobi manifolds, a concept that we had introduced in a previous Note. Twisted Jacobi manifolds can be characterized using twisted Dirac-Jacobi, which are sub-bundles of Courant-Jacobi algebroids. We show that each twisted Jacobi manifold has an associated Lie algebroid with a 1-cocycle. We introduce the notion of quasi-Jacobi bialgebroid and we prove that each twisted Jacobi manifold has a quasi-Jacobi bialgebroid canonically associated. Moreover, the double of a quasi-Jacobi bialgebroid is a Courant-Jacobi algebroid. Several examples of twisted Jacobi manifolds and twisted Dirac-Jacobi structures are presented. | URI: | https://hdl.handle.net/10316/11347 | Direitos: | openAccess |
