An extension of Seliger's wave breaking condition for the nonlocal Whitham type equation
Yongki Lee
We extend the wave breaking condition in Seliger's work [Proc. R. Soc. Lond. Ser. A., 303 (1968)], which has been used widely to prove wave breaking phenomena for nonlinear nonloca…

On the Riccati dynamics of 2D Euler-Poisson equations with attractive forcing
Yongki Lee
The Euler-Poisson (EP) system describes the dynamic behavior of many important physical flows. In this work, a Riccati system that governs two-dimensional EP equations is studied.…
