| Nov 28, 2019 at 20:07 | comment | added | reduced team | I just give a fast read to the paper and I understand why the system that we have is essentially the same. Basically we obtained our system using the hamiltonian formulation of General relativity, because we would like to fix a coordinates system in which the metric is diagonal using three diffeomorphisms, whose generator in the Hamiltonian formulation are the functions $N_i$ and the coefficients that I call $f_i$ are exactly the diagonal metric components. Your reference was like a gift, I searched a lot about this problem but I found basically nothing. Thank you again | |
| Nov 28, 2019 at 18:52 | comment | added | reduced team | First of all thank you for such an usefull answer, to understand if we can reformulate the problem as in the paper that you cited I think that I have to read the paper, because that system has a precise physical meaning so I have to understand what does it mean reformulate it into another system, which, if I understood correctly has different mathematical properties at least. I will read the paper and I will let you know as soon as possible. Thank you very much for your time and help! | |
