I am reading the paper "Covariant Action for a D=11 Five-Brane with the Chiral Field" and want to make an analog for the chiral field in 2 dimensions.(adsbygoogle = window.adsbygoogle || []).push({});

But I don't know at the starting point, for if I take the local coordinates of the worldvolume to be ##x^m (m=0,1)##, the dual field strength ##F_{mnl}## will be zero and the action ##S## becomes ##S=\int d^2x\sqrt{-g}##.

Could anyone give me some advices?

Best Regards.
