Methods of the theory of critical points at infinity on Cauchy Riemann manifolds

Sub-Riemannian spaces are spaces whose metric structure may be viewed as a constrained geometry, where motion is only possible along a given set of directions, changing from point to point. The simplest example of such spaces is given by the so-called Heisenberg group. The characteristic constrained motion of sub-Riemannian spaces has numerous applications in robotic control in...

The impact of the flatness condition on the prescribed Webster scalar curvature

In this paper, we give existence and multiplicity results for the problem of prescribing the Webster scalar curvature on the three CR sphere of \(\mathbb{C}^{2}\) under mixed conditions: non-degenerancy and flatness.
