我们提出了一个分类的传递顶点代数胚的光滑品种X进行的精神Bressler的分类的柯朗代数胚。特别是,我们计算类的堆栈的传递顶点代数胚。我们定义了在\cite{AChM}中引入的扭曲手征微分算子层的变形,并利用分类结果来描述和分类这种变形。作为特例,我们得到了旗流形上Wakimoto模在非临界水平上的局部化。
We present a classification of transitive vertex algebroids on a smooth variety X carried out in the spirit of Bressler's classification of Courant algebroids. In particular, we compute the class of the stack of transitive vertex algebroids. We define deformations of sheaves of twisted chiral differential operators introduced in \cite{AChM} and use the classification result to describe and classify such deformations. As a particular case, we obtain a localization of Wakimoto modules at non-critical level on flag manifolds.
