摘要
We derive conservation laws front interactions of braid-like excitations of embedded framed spin networks in quantum gravity. We also demonstrate that the set of stable braid-like excitations form a noncommutative algebra under braid interaction, in which the set of actively-interacting braids is a subalgebra.
