Abstract:
We show that discrete torsion is implemented in a D-brane world-volume theory by using a projective representation of the orbifold point group. We study the example of C^3/Z_2 x Z_2 and show that the resolution of singularities agrees with that proposed by Vafa and Witten. A new type of fractional brane appears.
  • membrane model: D-brane
  • field theory: orbifold
  • symmetry: Z(2) x Z(2)
  • torsion: discrete
  • coset space
  • membrane model: fractional
