Sign-changing solutions for the stationary Kirchhoff problems involving the fractional Laplacian in \mathcal{R}^N
Kun Chang, Qi Gao
In this paper, we study the existence of least energy sign-changing solutions for a Kirchhoff-type problem involving the fractional Laplacian operator. By using the constraint vari…

Stability of symmetric vortices for two-component Ginzburg-Landau systems
Stan Alama, Qi Gao
We study Ginzburg-Landau equations for a complex vector order parameter. We consider the Dirichlet problem in the disk in the plane with a symmetric, degree-one boundary condition,…

Symmetric vortices for two-component Ginzburg-Landau systems
Stan Alama, Qi Gao
We study Ginzburg--Landau equations for a complex vector order parameter Psi=(psi_+,psi_-). We consider symmetric (equivariant) vortex solutions in the plane R^2 with given degrees…
