关于SL(2,C)的余紧格的不可约表示的向量丛

On the vector bundles associated to irreducible representations of cocompact lattices of SL(2,C)

Indranil Biswas, Avijit Mukherjee

摘要:

在\cite{BM}的这一推广中,我们证明了以下几点:设$Γ\subset \text{SL}(2,{\mathbb C})$是一个余紧格,而$ρ: Γ\rightarrow \text{GL}(r,{\mathbb C})$是一个不可约表示。则与$ρ$相关联的全纯向量丛$E_ρ\longrightarrow \text{SL}(2,{\mathbb C})/Γ$是多稳定的。紧致复流形$\text{SL}(2,{\mathbb C})/Γ$具有自然的厄米特结构,$E_ρ$的多稳定性是关于这些自然的厄米特结构的.

英文摘要:

In this continuation of \cite{BM}, we prove the following: Let $Γ\subset \text{SL}(2,{\mathbb C})$ be a cocompact lattice, and let $ρ: Γ\rightarrow \text{GL}(r,{\mathbb C})$ be an irreducible representation. Then the holomorphic vector bundle $E_ρ\longrightarrow \text{SL}(2,{\mathbb C})/Γ$ associated to $ρ$ is polystable. The compact complex manifold $\text{SL}(2,{\mathbb C})/Γ$ has natural Hermitian structures; the polystability of $E_ρ$ is with respect to these natural Hermitian structures.
