On the V-states for the generalized quasi-geostrophic equations

We prove the existence of the V-states for the generalized inviscid SQG equations with $\alpha \in ]0,1[\mathrm{.}$ These structures are special rotating simply connected patches with $m-$ fold symmetry bifurcating from the trivial solution at some explicit values of the angular velocity. This produces, inter alia, an infinite family of non stationary global solutions with uniqueness.
