Probing AdS_{3}CFT correspondence via worldsheet methods and 2D gravitylike scaling arguments
Abstract
We show how some features of the AdSCFT correspondence for AdS_{3} can easily be understood via standard worldsheet methods and 2D gravitylike scaling arguments. To do this, we propose a stringy way for perturbing twodimensional CFT's around their critical points. Our strategy is to start from a stringy (worldsheet) representation of 2D CFT in spacetime. Next we perturb a worldsheet action by some marginal operators such that the spacetime symmetry becomes finite dimensional. As a result, we get a massive FT in spacetime with a scale provided by the twodimensional coupling constant. It turns out that there exists a perturbation that leads to string theory on AdS_{3}. In this case the scale is equivalently provided by the radial antide Sitter coordinate.
