Abstract: In lattice gauge theory, there exist field transformations that map thetheory to the trivial one, where the basic field variables are completelydecoupled from one another. Such maps can be constructed systematically byintegrating certain flow equations in field space. The construction is workedout in some detail and it is proposed to combine the Wilson flow whichgenerates approximately trivializing maps for the Wilson gauge action with theHMC simulation algorithm in order to improve the efficiency of lattice QCDsimulations.
