多维仿射代数和维拉索罗代数的离壳表示的新推导

New Derivation of Off-Shell Representations of the Multi-dimensional Affine and Virasoro Algebras

T. A. Larsson

摘要:

任意维的流代数和单同态代数的扩张推广了圆上的仿射代数和维拉索罗代数。在Comm.Math.Phys.214(2000)469- 491中发现了一大类离壳表示。由于稍微不标准的正态排序形式主义和繁琐的$p$ -jet计算,该论文并不那么容易理解。本论文的目的是简化使用标准的OPE方法和更像场的形式主义的推导。

英文摘要:

Algebras of currents and diffeomorphisms in arbitrary dimension have extensions which generalize the affine and Virasoro algebras on the circle. A large class of off-shell representations was discovered in Comm. Math. Phys. 214 (2000) 469--491. That paper is not so accessible due to a slightly non-standard normal ordering formalism and cumbersome $p$-jet calculations. The purpose of the present paper is to simplify the derivation using standard OPE methods and a more field-like formalism.
