Symmetrical Symplectic Capacity with Applications
Chungen Liu, Qi Wang
In this paper, we first introduce the concept of symmetrical symplectic capacity for symmetrical symplectic manifolds, and by using this symmetrical symplectic capacity theory we p…
Existence of Nontrivial Solutions for p-Laplacian Equations in {R}^{N}
Chungen Liu, Youquan Zheng
In this paper, we consider a p-Laplacian equation in {R}^{N}with sign-changing potential and subcritical p-superlinear nonlinearity. By using the cohomological linking method for c…
Linking Solutions for p-Laplace Equations with Nonlinear Boundary Conditions and Indefinite Weight
Chungen Liu, Youquan Zheng
We apply the linking method for cones in normed spaces to p-Laplace equations with various nonlinear boundary conditions. Some existence results are obtained.
Soliton solutions for coupled Schrodinger systems with sign-changing potential
Chungen Liu, Youquan Zheng
In this paper, a class of coupled systems of nonlinear Schrodinger equations with sign-changing potential, including the linearly coupled case, is considered. The existence of non-…
