Abstract:
We give an example of an Engel structure on the 4-dimensional Euclidean space which admits a compact characteristic leaf. We also show that every Engel structure on an open 4-manifold can be modified so that the resulting structure has a compact characteristic leaf.

Abstract:
AbstractWe consider the Dirichlet-to-Neumann operator associated to a strictly elliptic operator on the space $$\mathrm {C}(\partial M)$$ C ( ∂ M ) of continuous functions on the boundary $$\partial M$$ ∂ M of a compact manifold $$\overline{M}$$ M ¯ with boundary. We prove that it generates an analytic semigroup of angle $$\frac{\pi }{2}$$ π 2 , generalizing and improving a result of Escher with a new proof. Combined with the abstract theory of operators with Wentzell boundary conditions developed by Engel and the author, this yields that the corresponding strictly elliptic operator with Wentz

Abstract:
Ce mémoire est une contribution à la résolution du problème d'équivalence pour les variétés de Cauchy-Riemann en dimension inférieure ou égale à 5. On traite d'abord du cas des variétés CR de dimension 5, qui sont 2-nondégénérées et de rang de Levi constant égal à 1. Pour une telle variété, on obtient deux invariants, J et W, dont l'annulation simultanée caractérise l'équivalence locale à une variété modèle, le tube au-dessus du cône de lumière. Si l'un des deux invariants ne s'annule pas, on construit un parallélisme absolu, i.e. on montre que le problème d'équivalence se réduit à un problème
