论文摘要
我们开发了一种基于流的采样算法，用于$ su（n）$ lattice仪表理论，该算法是通过构造量规范的。我们的关键贡献是在$ SU（n）$ variable（或通过简单替代方案的$ u（n）$变量上构建一类流量，以尊重矩阵共轭对称性。我们将此技术应用于单个$ SU（N）$变量的样本分布，并在二维中构建基于流的采样器（2）$（2）$（2）$（2）$（3）$ lattice Gauge理论。
We develop a flow-based sampling algorithm for $SU(N)$ lattice gauge theories that is gauge-invariant by construction. Our key contribution is constructing a class of flows on an $SU(N)$ variable (or on a $U(N)$ variable by a simple alternative) that respect matrix conjugation symmetry. We apply this technique to sample distributions of single $SU(N)$ variables and to construct flow-based samplers for $SU(2)$ and $SU(3)$ lattice gauge theory in two dimensions.
