Hamiltonian analysis of the double null 2+2 decomposition of Ashtekar variables
This algebra has a similar form to that obtained by Goldberg et al. but is simpler because in our 2+2 case G generates the self-dual spin and boost transformations rather than the more complicated null rotations which are needed in the null 3+1 setting.
Hamiltonian analysis of the double null 2+2 decomposition of Ashtekar variables
For some cardinal κ, we say that a measure ν is κ-additive to indicate that add(ν ) ≥ κ. A measurable set E ⊆ X is called an atom if it is not null and every F ⊆ E with µ(F ) < µ(E ) is null; similarly, for a nonzero element of a measure algebra.
