Stationary homogeneous solutions for the inviscid SQG equation
Abstract
In this paper, we prove the existence of nontrivial stationary homogeneous solutions with infinite energy (unbounded at infinity) for the SQG equation. Our analysis also covers the existence of stationary solutions for the generalized De Gregorio equation $\partial_t w+\alpha u\,\partial_x w= w\,\partial_x u,\ \partial_x u=Hw$ with $\alpha>\tfrac{1}{2}$, where $H$ denotes the Hilbert transform.
