D-branes and discrete torsion
Jul, 1998Citations per year
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
