Centers and invariant straight lines of planar real polynomial vector fields and its configurations
Hongjin He, Changjian Liu, Dongmei Xiao
In the paper, we first give the least upper bound formula on the number of centers of planar real polynomial Hamiltonian vector fields. This formula reveals that the greater the nu…
Rotating shallow water equations with bottom drag: bifurcations and growth due to kinetic energy backscatter
Artur Prugger, Jens D. M. Rademacher, Jichen Yang
The rotating shallow water equations with f-plane approximation and nonlinear bottom drag are a prototypical model for mid-latitude geophysical flow that experience energy loss thr…
