Academy of Mathematics and Systems Science, CAS Colloquia & Seminars：Regularity of sub-elliptic harmonic map into non-positively curved metric space

2023/4/28
We prove the Holder continuity of a harmonic map from a domain of a sub-Riemannian manifold into a locally compact manifold with non-positive curvature, and more generally into a non-positively curved...

Stability of Stationary Wave Maps Curved Background Sphere
2012/4/18
We study time and space equivariant wave maps from $M\times\RR\rightarrow S^2,$ where $M$ is diffeomorphic to a two dimensional sphere and admits an action of SO(2) by isometries. We assume that metri...

QFT on homothetic Killing twist curved spacetimes
2010/11/30
We study the quantum field theory (QFT) of a free, real and massless scalar field on self-similar symmetric spacetimes, which are deformed by an abelian Drinfel’d twist constructed
from a Killing and...
