Loop Variables and the Virasoro Group | | B. Sathiapalan

15 Jul 1992 | | Journal: | Nucl. Phys. B405 (1993) 367 | | Subject: | hep-th | | Abstract: | We derive an expression in closed form for the action of a finite element of the Virasoro Group on generalized vertex operators. This complements earlier results giving an algorithm to compute the action of a finite string of generators of the Virasoro Algebra on generalized vertex operators. The main new idea is to use a first order formalism to represent the infinitesimal group element as a loop variable. To obtain a finite group element it is necessary to thicken the loop to a band of finite thickness. This technique makes the calculation very simple. | | Source: | arXiv, hep-th/9207051 | | Services: | Forum | Review | PDF | Favorites | |
