Gravitation and quadratic forms
Gravitation and quadratic forms
The light-cone Hamiltonians describing both pure ( $$ \mathcal{N} $$ = 0) Yang-Mills and $$ \mathcal{N} $$ = 4 super Yang-Mills may be expressed as quadratic forms. Here, we show that this feature extends to theories of gravity. We demonstrate how the Hamiltonians of both pure gravity and $$ \mathcal{N} …
