This note studies invariant generators for a certain class of invariant smooth generalized subbundles of exact Courant algebroids, which generalizes existing results for invariant vector subbundles of exact Courant algebroids. As a result, we provide a simple and geometric proof for Theorem 1 in [1].

关于广义子束不变生成器的注记

本文研究了精确库仑代数的一类不变光滑广义子集的不变生成器，它推广了精确库仑代数的不变矢量子集的现有结果。结果，我们为[1]中的定理1提供了简单的几何证明。
