$TM\o加上T^*M$的共形变换是形式为$(X,\alpha)\mapsto(X,e^\tau\alpha)$ $(X\in TM,\alpha\in T^*M,\tau\in C^\infty(M))$的态射。我们分别刻画了局部共形于可积结构和广义K 'ahler结构的广义几乎复结构和几乎埃尔米特结构,并给出了此类结构的例子。
A conformal change of $TM\oplus T^*M$ is a morphism of the form $(X,\alpha)\mapsto(X,e^\tau\alpha)$ $(X\in TM,\alpha\in T^*M,\tau\in C^\infty(M))$. We characterize the generalized almost complex and almost Hermitian structures that are locally conformal to integrable and to generalized K\"ahler structures, respectively, and give examples of such structures.
