  1. This alone would not be an improvement over point particle versions of quantum gravity except that it is possible to define a perturbative expansion of string theory around a fixed, classical background space-time that is finite and anomaly free at 1-loop
  2. In the critical dimension the world-sheet gravity decouples from the matter or embedding fields
  3. Does anyone know what happened to Lubos Motl?

    I am happy to discuss in this thread
  4. The partition function can be evaluated as a perturbation series which consists of terms like genus 0 [to the superconformal anomaly]

    Hey Prashant,

    The above messages are but noise. You are welcome to interact here appropriately, but if you intend to continue in this manner you should take this activity to another venue.

  6. When λ \lambda is small we can use perturbation theory to find an approximate expression for G(x,t;x 0,t 0) G(x, t; x_0 , t_0 )

    I hope I am allowed to start a new entry on the nlab main page
