调和函数通过compact Riemann surfaces上拟圆的传递

Transmission of harmonic functions through quasicircles on compact Riemann surfaces

Eric Schippers, Wolfgang Staubach

摘要:

设$R$是紧致曲面,$Γ$是将$R$分解为两个连通分支$Σ_1$和$Σ_2$的Jordan曲线.有界Dirichlet范数的$Σ_1$上的调和函数$h_1$在$Γ$上的某个保形不变的非切向意义下具有边界值$H$.证明了若$Γ$是拟圆,则在$Σ_2$上存在唯一的有界Dirichlet范数的调和函数$h_2$,其边界值与$h_1$的边界值一致.此外,从$Σ_1$的Dirichlet空间到$Σ_2$的映射关于Dirichlet半范数是有界的。

英文摘要:

Let $R$ be a compact surface and let $Γ$ be a Jordan curve which separates $R$ into two connected components $Σ_1$ and $Σ_2$. A harmonic function $h_1$ on $Σ_1$ of bounded Dirichlet norm has boundary values $H$ in a certain conformally invariant non-tangential sense on $Γ$. We show that if $Γ$ is a quasicircle, then there is a unique harmonic function $h_2$ of bounded Dirichlet norm on $Σ_2$ whose boundary values agree with those of $h_1$. Furthermore, the resulting map from the Dirichlet space of $Σ_1$ into $Σ_2$ is bounded with respect to the Dirichlet semi-norm.
