Gravitation and quadratic forms
Sudarshan Ananth, Lars Brink, Sucheta Majumdar +2
The light-cone Hamiltonians describing both pure Yang-Mills and N=4 super Yang-Mills may be expressed as quadratic forms. Here, we show that this feature extends to theories of gra…

Yang-Mills theories and quadratic forms
Sudarshan Ananth, Lars Brink, Mahendra Mali
We show that the Hamiltonian of (N=1;d=10) super Yang-Mills can be expressed as a quadratic form in a very similar manner to that of the (N=4;d=4) theory. We find a similar quadrat…

Light-cone gravity in dS
Sudarshan Ananth, Mahendra Mali
We derive a closed form expression for the light-cone Lagrangian describing pure gravity on a four-dimensional de Sitter background. We provide a perturbative expansion, of this La…
