Coisotropic characteristic classes
Article [Accepted Manuscript]
Abstract(s)
In this paper, we introduce coisotropic characteristic classes in order to study coisotropic
immersions in Cn, and prove that they actually are the isotropic classes introduced by Lalonde
(Math Ann 285:343–351, 1989). We conclude with some remarks on the differences between
the h-principles for coisotropic immersions, and the one for isotropic immersions that the
coisotropic classes fail to capture. Dans cet article, nous introduisons des classes caractéristiques coisotropes afin d’étudier les immersions coisotropes dans Cn et démontrons qu’elles sont en réalité les classes isotropes introduites par Lalonde (1989). Nous concluons par une discussion sur les différences entre le h-principe pour les immersions isotropes et celui pour les immersions coisotropes que les classes coisotropes n’arrivent pas à détecter.
