Existence of solutions to perturbed fractional Nirenberg problems

Existence of solutions to perturbed fractional Nirenberg problems

In this article we study a fractional Nirenberg problem with a small perturbation of a constant. Under a flatness assumption around the critical points, we prove an existence result in terms of Euler-Hopf index. Our method hinges on a revisited version of the celebrated critical points at infini...
