Abstract
It is shown that, in a non-Abelian quantum field theory without an anomaly and broken symmetry, the set of all matrix-valued quantum holonomies for closed contours form a commutative semigroup, whereas for every open path . The eigenvalues of are classified according to the irreducible representations of the gauge group. In an irreducible representation , is a Wilson loop. This equation solves a puzzle in the relation between link invariants and Wilson loops in the Chern-Simons theory in three dimensions when the gauge group is , and provides useful insight in understanding nonperturbative quantum chromodynamics as a string theory.
