Abstract: It is an expository talk about the work of François Hamel and Nikolai Nadirashvili in 2017. They proved that, in a two-dimensional strip, a steady flow of Euler equations with tangential boundary conditions and with no stationary point is a shear flow. The proof is based on the study of geometric properties of the streamlines of the flow and on one-dimensional symmetry results for solutions of some semi-linear elliptic equations.
