Dear All
I am interested in studying the ADM formalism for gravity theories. After finding the momentum and getting rid of the time derivative variables ,One of the steps is to write the hamiltonian as sum of 2 parts of coefficients the lapse and shift functions repectively H= N H_t + N_i H_i.
My question is that what if the Hamiltonian is not linear in N and N_i.?
\Thank you
