李叶理的自同态群

The diffeomorphism group of a Lie foliation

G. Hector, E. Macías-Virgós, A. Sotelo-Armesto

摘要:

我们明确计算的几种类型的线性叶理(密集的叶子)的环面$T^n$,$n\geq 2$,即余维一叶理,流,和所谓的非二次叶理的同胚群。我们特别表明,非二次叶理是刚性的,在这个意义上说,他们不承认横向同胚以外的$\pm \id$和翻译。计算是一个通用的公式,我们证明了一个紧凑的流形上的任何李叶理稠密的叶的同胚群的应用。我们的结果推广了P.Donato和P.Iglesias对$T^2$,P.Iglesias和G. Lachaud对$T^n$,$n\geq 2$和B上的余维1叶理进行了研究. Herrera为卓越的叶理。本文的理论背景是J.M. Souriau的空间理论

英文摘要:

We explicitly compute the diffeomorphism group of several types of linear foliations (with dense leaves) on the torus $T^n$, $n\geq 2$, namely codimension one foliations, flows, and the so-called non-quadratic foliations. We show in particular that non-quadratic foliations are rigid, in the sense that they do not admit transverse diffeomorphisms other than $\pm \id$ and translations. The computation is an application of a general formula that we prove for the diffeomorphism group of any Lie foliation with dense leaves on a compact manifold. Our results generalize those of P. Donato and P. Iglesias for $T^2$, P. Iglesias and G. Lachaud for codimension one foliations on $T^n$, $n\geq 2$, and B. Herrera for transcendent foliations. The theoretical setting of the paper is that of J. M. Souriau's diffeological spaces.
