Decomposition Theorems for Groups of Diffeomorphisms in the Sphere
نویسنده
چکیده
We study the algebraic structure of several groups of differentiable diffeomorphisms in Sn. We show that any given sufficiently smooth diffeomorphism can be written as the composition of a finite number of diffeomorphisms which are symmetric under reflection, essentially one-dimensional and about as differentiable as the given one.

Diffeomorphism groups of balls and spheres
In this paper we discuss the relationship between groups of diffeomorphisms of spheres and balls. We survey results of a topological nature and then address the relationship as abstract (discrete) groups. We prove that the identity component of the group of smooth diffeomorphisms of an odd dimensional sphere admits no nontrivial homomorphisms to the group of diffeomorphisms of a ball of any dim...
متن کاملDecomposing Diffeomorphisms of the Sphere
A central problem in the theory of quasiconformal and biLipschitz mappings is whether they can be written as a composition of such mappings with small distortion. In this paper we prove a decomposition result for C diffeomorphisms of the sphere. Namely we show that given > 0, every C diffeomorphism of the sphere S can be written as a composition of bi-Lipschitz mappings with isometric distortio...
متن کاملReduction of cocycles and groups of diffeomorphisms of the circle
We prove two theorems of reduction of cocycles taking values in the group of diffeomorphisms of the circle. They generalise previous results obtained by the author concerning rigidity for smooth actions on the circle of Kazhdan’s groups and higher rank lattices.

متن کاملSub-Riemannian structures on groups of diffeomorphisms
In this paper, we define and study strong right-invariant sub-Riemannian structures on the group of diffeomorphisms of a manifold with bounded geometry. We derive the Hamiltonian geodesic equations for such structures, and we provide examples of normal and of abnormal geodesics in that infinite-dimensional context. The momentum formulation gives a sub-Riemannian version of the Euler-Arnol’d equ...
متن کاملOn the Classification of Finite Groups Acting on Homology 3-spheres
In previous work we showed that the only finite nonabelian simple group acting by diffeomorphisms on a homology 3sphere is the alternating or dodecahedral group A5. Here we characterize finite nonsolvable groups that act on a homology 3-sphere preserving orientation. We find exactly the finite nonsolvable groups that act orthogonally on the 3-sphere, plus two families of groups for which we do ...
