Periodic and quasi-periodic Euler- flows close to Rankine vortices
Emeric Roulley
In the present contribution, we first prove the existence of -fold simply-connected V-states close to the unit disc for Euler- equations. These solutions are implici…

Boundary effects on the emergence of quasi-periodic solutions for Euler equations
Zineb Hassainia, Emeric Roulley
In this paper, we highlight the importance of the boundary effects on the construction of quasi-periodic vortex patches solutions close to Rankine vortices and whose existence is n…

Vortex rigid motion in quasi-geostrophic shallow-water equations
Emeric Roulley
In this paper, we prove the existence of relative equilibria with holes for quasi-geostrophic shallow-water equations. More precisely, using bifurcation techniques, we establish fo…
