  1. Aspinwall, PS, A note on the equivalence of Vafa's and Douglas's picture of discrete torsion, Journal of High Energy Physics, vol. 4 no. 12 (December, 2000), pp. 029-029, Springer Nature [hep-th/0009045], [doi] .

    For a general non-abelian group action and an arbitrary genus worldsheet we show that Vafa's old definition of discrete torsion coincides with Douglas's D-brane definition of discrete torsion associated to projective representations.
