nLab RR-field tadpole cancellation on toroidal orientifolds -- table

RR-field tadpole cancellation conditions for D-branes wrapped on toroidal orientifolds
in terms of their D-brane charge VK G(*)=R GV \in K_G(\ast) = R_G in equivariant K-theory = representation ring
(here n reg=k[G/1]\mathbf{n}_{reg} = k[G/1] denotes the regular representation of dimension n=n = ord(G))
