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 C³/Z₂ x Z₂ and show that the resolution of singularities agrees with that proposed by Vafa and Witten. A new type of fractional brane appears.
