We define gauge transformations of Jacobi structures on a manifold. This is related to gauge transformations of Poisson structures via the Poissonization. Finally, we discuss how the contact structure of a contact groupoid is effected by a gauge transformation of the Jacobi structure on its base.

雅可比结构和接触群体的规范变换

我们定义流形上雅可比结构的规范变换。这与通过泊松化对泊松结构的规范变换有关。最后，我们讨论了接触群的接触结构如何受其基础上的雅可比结构的规范变换的影响。
