Weakened vortex stretching effect in three scale hierarchy for the 3D Euler equations
In-Jee Jeong, Jungkyoung Na, Tsuyoshi Yoneda
We consider the 3D incompressible Euler equations under the following three scale hierarchical situation: large-scale vortex stretching the middle-scale, and at the same time, the…
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…
Global well-posedness for a two-dimensional Keller-Segel-Euler system of consumption type
Jungkyoung Na
We consider the Cauchy problem for the Keller-Segel system of consumption type coupled with the incompressible Euler equations in . This coupled system describes a bi…
Finite-time blow-up to hyperbolic Keller-Segel system of consumption type with logarithmic sensitivity
Jungkyoung Na
This paper deals with a hyperbolic Keller-Segel system of consumption type with the logarithmic sensitivity \begin{equation*} \partial_{t} ρ= - χ\nabla \cdot \left (ρ\nabla \log c\…
