    We write down a general action principle for spinning strings in (2+1)-dimensional space-time without introducing Grassmann variables. The action is written solely in terms of coordinates taking values in the 2+1 Poincaré ...
  • Fabi, S.; Harms, B.; Stern, Allen (2008-09-23)
    Upon applying Chamseddine’s noncommutative deformation of gravity, we obtain the leading order noncommutative corrections to the Robertson-Walker metric tensor. We get an isotropic inhomogeneous metric tensor for a certain ...
