چکیده
The observations in this talk come from a paper in preparation by A. Čap, M. Cowling, F. De Mari, M. Eastwood and R. McCallum about the Heisenberg group and the flag manifold, and more general papers by Cowling, De Mari, A. Korányi and H.M. Reimann, one published [?] and one in preparation, as well as papers by McCallum (in preparation) and B. Warhurst [?]. A Carnot group N is a connected, simply connected nilpotent Lie group whose Lie algebra n is stratified, that is

Regularity Results for Quasilinear Degenerate Elliptic Obstacle Problems in Carnot Groups
Let {X1, . . . , Xm} be a basis of the space of horizontal vector fields on the Carnot group G = (R , ◦)(m < N). We establish regularity results for solutions to the following quasilinear degenerate elliptic obstacle problem ∫ Ω 〈〈AXu,Xu〉 p−2 2 AXu,X(v − u)〉dx ≥ ∫ Ω B(x, u,Xu)(v − u)dx
متن کاملHausdorff Measure of the Singular Set of Quasiregular Maps on Carnot Groups
Recently, the theory of quasiregular mappings on Carnot groups has been developed intensively. Let ν stand for the homogeneous dimension of a Carnot group and let m be the index of the last vector space of the corresponding Lie algebra. We prove that the (ν −m− 1)-dimensional Hausdorff measure of the image of the branch set of a quasiregular mapping on the Carnot group is positive. Some estimat...
متن کاملTangent bundles to sub-Riemannian groups
1 1 INTRODUCTION 2 1 Introduction Classical calculus is a basic tool in analysis. We use it so often that we forget that its construction needed considerable time and effort. Especially in the last decade, the progresses made in the field of analysis in metric spaces make us reconsider this calculus. Along this line of thought, all started with the definition of Pansu derivative [24] and its ve...
متن کاملRemarks about Besicovitch Covering Property in Carnot Groups of Step 3 and Higher
We prove that the Besicovitch Covering Property (BCP) does not hold for some classes of homogeneous quasi-distances on Carnot groups of step 3 and higher. As a special case we get that, in Carnot groups of step 3 and higher, BCP is not satisfied for those homogeneous distances whose unit ball centered at the origin coincides with a Euclidean ball centered at the origin. This result comes in con...
متن کاملIntegrable geodesic flows of non-holonomic metrics
In the present article we show how to produce new examples of integrable dynamical systems of differential geometry origin. This is based on a construction of a canonical Hamiltonian structure for the geodesic flows of Carnot–Carathéodory metrics ([7, 17]) via the Pontryagin maximum principle. This Hamiltonian structure is achieved by introducing Lagrange multipliers bundles being the phase spa...
