The basic variables are taken to be the induced metric q a b on the spatial slice and the metric's conjugate momentum K a b , which is related to the extrinsic curvature and is a measure of how the induced metric evolves in time. These are the metric canonical coordinates. In 1986 Abhay Ashtekar introduced a new set of canonical variables, Ashtekar (new) variables to represent an unusual way of
