Abstract

In this paper, an attempt is made to represent 5+1 dimensional gravity (via ADM formalism) in terms of the loop constructions introduced by the author in a companion paper. The "momenta" and "velocity" from the earlier paper, which were proven to be cobordant loops in 6 D; are used as the new loop variables. In the process, the Hamiltonian, Diffeomorphism and Gauss constraints are written in polynomials of these loop variables. Other constraints such as the "Q" constraint and simplicity constraints arise due to greater degrees of freedom. We then undergo the Master Constraint treatment to resolve the constraints. Then, a pre-quantum version of the theory is examined; and the properties of the Grassmannian of the Hilbert Space are explored.
