A Course on Noncommutative Geometry in String Theory

In this pedagogical mini course the basics of the derivation of the noncommutative structures appearing in string theory are reviewed. First we discuss the well established appearance of the noncommutative Moyal-Weyl star-product in the correlation functions of open string vertex operators on a magnetized D-brane. Second, we will review the most recent attempts to generalize these concepts to the closed string moving in a nongeometric flux background.
