Strict Deformation Quantisation of the G-connections via Lie Groupoid

Motivated by the compactification process of the space of connections in loop quantum gravity literature. A description of the space of G-connections using the tangent groupoid is given. As the tangent groupoid parameter is away from zero, the G-connections are (strictly) deformation quantised to noncommuting elements using C*-algebraic formalism. The approach provides a mean to obtaining a semi-classical limit in loop quantum gravity.
