* ABSTRACT | |||||||
In arXiv:0801.0218 [hep-th] it was conjectured that quantum effects of open strings moving on D-branes generate the D-brane geometry through a counter- vertex operator. The conjecture was checked at one-loop in arXiv:0806.3330 [hep-th]. The two-loop extension has been made in arXiv:0902.1279 [hep-th]. With the development of the pure spinor formulation, the three-loop analysis seems within reach. We discuss aspects of the three-loop analysis |
