紧Hermite对称空间上几乎全纯截面的存在性

Existence of nearly holomorphic sections on compact Hermitian symmetric spaces

Benjamin Schwarz

摘要:

设$X=U/K$是紧致的厄米特对称空间,$\sE$是$X$上的$U$ -齐次厄米特向量丛.在以前的论文中,我们表明,几乎全纯部分的空间是非常适合调和分析$L^2(X,\sE)$提供非平凡的几乎全纯部分确实存在。本文研究了局部近似全纯截面到整体近似全纯截面的推广问题,证明了非平凡近似全纯截面的存在性。这推广了我们在前一篇文章中关于$L^2(X,\sE)$的$U$型分解的结果.

英文摘要:

Let $X=U/K$ be a compact Hermitian symmetric space, and let $\sE$ be a $U$-homogeneous Hermitian vector bundle on $X$. In a previous paper, we showed that the space of nearly holomorphic sections is well-adapted for harmonic analysis in $L^2(X,\sE)$ provided that non-trivial nearly holomorphic sections do exist. Here we investigate the problem of extending local nearly holomorphic sections to global ones and prove the existence of non-trivial nearly holomorphic sections. This extends the results on the $U$-type decomposition of $L^2(X,\sE)$ from our previous paper.
