This is written in Brinkman coordinates as:
ds squared = - A du squared - 2 dudv + dr squared + r sqaured d theta squared ———— (1)
where:
A = - 4 m a loge sub e (r) / (pi (1 + a squared u squared))
where
- infinity
I think that this one also will fail the dual identity test. It is used in the context of black holes, and it is claimed that it resolves a paradox. These Wikipedia claims are as clear as mud, and we may as well give the coup de grace to this metric too.
