Illposedness via degenerate dispersion for generalized surface quasi-geostrophic equations with singular velocities

Dongho Chae, In-Jee Jeong, Sung-Jin Oh

We prove strong nonlinear illposedness results for the generalized SQG equation in any sufficiently regular Sobolev spaces, w…

Well-posedness for Ohkitani model and long-time existence for surface quasi-geostrophic equations

Dongho Chae, In-Jee Jeong, Jungkyoung Na +1

We consider the Cauchy problem for the logarithmically singular surface quasi-geostrophic (SQG) equation, introduced by Ohkitani, $$\partial_t θ- \nabla^\perp \log(10+(-Δ)^{\frac12…
