从任意偶格的任意等距出发，引入了扭曲顶点算子和位移顶点算子。这些算子提供了扭仿射李代数的实现。这种构造，推广了许多已知的构造，是基于一种自包含的“演算”。"
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."
