我们介绍并且学习这个概念(弱) 为非局部的顶点代数学的 pseudotwistor,扭合器的观点的归纳。我们给在 pseudotwistors 和扭动的操作员之间的关系。而且,我们学习可颠倒的弱 pseudotwistor 的逆和二弱 pseudotwistors 的作文。
We introduce and study the concept of (weak) pseudotwistor for a nonlocal vertex algebra, as a generalization of the notion of twistor. We give the relations between pseudotwistors and twisting operators. Furthermore, we study the inverse of an invertible weak pseudotwistor and the composition of two weak pseudotwistors.
