Constant vorticity two-layer water flows in the -plane approximation with centripetal forces
Yuchao He, Yongli Song, Yonghui Xia
The constant vorticity {\bf two-layer water wave} in the -plane approximation with centripetal forces is investigated in this paper. Different from the works (Chu and Yang\cite[…
