The qualitative behavior at the free boundary for approximate harmonic maps from surfaces
Juergen Jost, Lei Liu, Miaomiao Zhu
Let be a sequence of maps from a compact Riemann surface with smooth boundary to a general compact Riemannian manifold with free boundary on a smooth submanifold…
Energy identity for a class of approximate Dirac-harmonic maps from surfaces with boundary
Juergen Jost, Lei Liu, Miaomiao Zhu
For a sequence of coupled fields from a compact Riemann surface with smooth boundary to a general compact Riemannian manifold with uniformly bounded energy and…
A global weak solution to the Lorentzian harmonic map flow
Xiaoli Han, Lei Liu, Liang Zhao
We investigate a parabolic-elliptic system which is related to a harmonic map from a compact Riemann surface with a smooth boundary into a Lorentzian manifold with a warped product…
Singularity of the -th eigenvalue of high dimensional Sturm-Liouville problems
Xijun Hu, Lei Liu, Li Wu +1
It is natural to consider continuous dependence of the -th eigenvalue on -dimensional () Sturm-Liouville problems after the results on -dimensional case by Kong, W…
Multiplicity of closed characteristics on -symmetric compact convex hypersurfaces in
Lei Liu, Li Wu
There is a long standing conjecture that there are at least closed characteristics for any compact convex hypersurface in , and the symmetric case, i.e. $Σ…
