Constructing Spacetime from the String Worldsheet
arXiv:0911.0599
Abstract
In a certain sense riemannian geometry can be thought of as geometry built up from the finslerian properties of point particles. The generalization of this to where the geometry is built up from the finslerian properties of string and membranes is investigated. Solely classical arguments suggest a physical interpretation in which microscopic strings are directly related to macroscopic geometry; alternatively the resulting geometry can be interpretated as that describing microsopic spacetime.
