Global bifurcation of water-wave fronts generated by surface pressure
Jifeng Chu, Zihao Wang, Yong Zhang
We study two-dimensional steady gravity water waves with general vorticity in a homogeneous, inviscid fluid of finite depth, subject to a surface pressure that tends to distinct co…
Optimal bounds for embedded eigenvalues of one-dimensional discrete Schrödinger operators with decaying potentials
Jifeng Chu, Wencai Liu, Kang Lyu
In this paper, we consider one-dimensional discrete Schrödinger operators \begin{align} Hu(n)=(Δ+V)u(n)\nonumber \end{align} on with a self-adjoint boundary co…
Large-Amplitude Steady Solitary Water Waves with General Vorticity
Jifeng Chu, Zihao Wang, Yong Zhang
We study two-dimensional steady solitary gravity water waves with general vorticity, allowing for overhanging free-surface profiles. The main challenges arise from the free boundar…
Weak separability and partial Fermi isospectrality of discrete periodic Schrödinger operators
Jifeng Chu, Kang Lyu, Chuan-Fu Yang
In this paper, we consider the discrete periodic Schrödinger operators on , where is -periodic with $Γ=q_1 \mathbb{Z}\oplus q_2\mathbb{Z}\oplus\cdots\oplus q_d\m…
Constant vorticity geophysical waves with centripetal forces and at arbitrary latitude
Jifeng Chu, Yanjuan Yang
We consider three-dimensional geophysical flows at arbitrary latitude and with constant vorticity beneath a wave train and above a flat bed in the -plane approximation with cent…
Nonuniform dichotomy spectrum and reducibility for nonautonomous equations
Jifeng Chu, Fang-Fang Liao, Stefan Siegmund +2
For nonautonomous linear differential equations with nonuniform hyperbolicity, we introduce a definition for nonuniform dichotomy spectrum, which can be seen as a generalization of…
