Camacho, C. (ed.) et al., Complex analytic methods in dynamical systems. Proceedings of the congress held at Instituto de Matemática Pura e Aplicada, IMPA, Rio de Janeiro, Brazil, January 1992. Paris: Société Mathématique de France, Astérisque. 222, 327-343 (1994).
The author proves the following Theorem: “Let \((M_i^n,{\mathcal F}_i)\), \(i=1, 2\), be a real analytic and orientable foliation of \(n\)- manifolds of codimension 1 and \(h: (M_1^n,{\mathcal F}_1)\to (M_2^n,{\mathcal F}_2)\) a foliation preserving homeomorphism. Assume that all leaves of \({\mathcal F}_1\) are dense and that there exists a leaf of \({\mathcal F}_1\) with holonomy group \(=1, \mathbb{Z}\). Then \(h\) is transversely real analytic.” The proof is based on a rigidity theorem for pseudogroups. As a natural interpretation of the work by E. Ghys and T. Tsuboi [Ann. Inst. Fourier 38, No. 1, 215-244 (1988; Zbl 0633.58018)], the author applies this theorem to prove a topological rigidity of the Godbillon-Vey class of real analytic foliations of codimension one.
