Abstract
We develop a flow-based sampling algorithm for lattice gauge theories that is gauge invariant by construction. Our key contribution is constructing a class of flows on an variable [or on a variable by a simple alternative] that respects matrix conjugation symmetry. We apply this technique to sample distributions of single variables and to construct flow-based samplers for SU(2) and SU(3) lattice gauge theory in two dimensions.
