Starting from an arbitrary isometry of an arbitrary even lattice, twisted and shifted vertex operators are introduced. Under commutators, these operators provide realizations of twisted affine Lie algebras. This construction, generalizing a number of known ones, is based on a self-contained "calculus."
从任意偶数格的任意等距开始,引入扭曲和移位顶点算子。在交换子下,这些算子提供了扭曲仿射李代数的实现。这种构造,概括了许多已知的构造,基于一个自包含的“计算”。
