我们将谱独立性的概念(由Anari,Liu和Oveis Gharan[4]引入)从布尔域推广到一般的离散域。这一性质描述了关联有限的分布,并暗示相应的Glauber动力学是快速混合的。作为一个具体的应用,我们证明了抽样适当的q-染色的Glauber动力学对于具有最大度Δ的无三角形图族在多项式时间内混合,其中≥(α*+δ)Δ1.763是α*≈*=exp(1/α*)的唯一解,而δ?0是任意常数。这是第一个在可能无界Δ的情况下采样适当Q-着色的有效算法。我们建立光谱独立性的主要工具是Goldberg、Martin和Paterson的递归耦合[25]。
We extend the notion of spectral independence (introduced by Anari, Liu, and Oveis Gharan [4]) from the Boolean domain to general discrete domains. This property characterises distributions with limited correlations and implies that the corresponding Glauber dynamics is rapidly mixing. As a concrete application, we show that Glauber dynamics for sampling proper q-colourings mixes in polynomial-time for the family of triangle-free graphs with maximum degree Δ provided q≥ (α* + δ)Δ where α*≈ 1.763 is the unique solution to α* = exp (1/α*) and δ Þ 0 is any constant. This is the first efficient algorithm for sampling proper q-colourings in this regime with possibly unbounded Δ. Our main tool of establishing spectral independence is the recursive coupling by Goldberg, Martin, and Paterson [25].
