Please tell me how to count the degree of freedom in ADM gravity.(adsbygoogle = window.adsbygoogle || []).push({});

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?
