The Resurgence of Instantons in String Theory

Aniceto, Inês, Schiappa, Ricardo, Vonk, Marcel

Understand

Nonperturbative effects in string theory are usually associated to D-branes.

  • In many cases it can be explicitly shown that D-brane instantons control the large-order behavior of string perturbation theory, leading to the well-known (2g)! growth of the genus expansion.
  • This paper presents a detailed treatment of nonperturbative solutions in string theory, and their relation to the large-order behavior of perturbation theory, making use of transseries and resurgent analysis.
  • These are powerful techniques addressing general nonperturbative contributions within non-linear systems, which are developed at length herein as they apply to string theory.
