by saying **F=-F, I assume you are working in a minkowski space with dimension
4, for which a self dual tensor does not exist for the reason you have just
said. a self/anti dual tensor will only exists if the rank of the tensor is
some odd number and the dimension is 2*rank (for lorentzian signature). for
example, we can have a self dual 3-form in dimension 6. |
