Please tell me how to count the degree of freedom in ADM gravity.
6 independent components of [tex]q_{ab}[/tex],
and 4 constraints
= 2 degrees of freedom
shouldn't it be
6 independent components of [tex]q_{ab}[/tex]
implies 12 phase space variables
4 constraints
=8 phase space variables
=4 degrees of freedom?
