反铁磁伊辛模型超越链图
The antiferromagnetic Ising model beyond line graphs
AI总结:
本文研究了反铁磁伊辛模型在链图之外的扩展性,发现其在无爪图等结构上不可行,而硬核心模型则具有更广泛的可处理性。
摘要:
反铁磁伊辛模型和硬核心模型都能在度数有界的链图上被有效处理。例如,Glauber动力学在两种情况下都能快速混合。在硬核心模型的情况下,我们已知其可扩展到无爪图并稍作扩展。相比之下,本文显示在反铁磁伊辛模型的情况下,这种扩展是不可能的。
英文摘要:
Both the antiferromagnetic Ising model and the hard-core model could be said to be tractable on line graphs of bounded degree. For example, Glauber dynamics is rapidly mixing in both cases. In the case of the hard-core model, we know that tractability extends further, to claw-free graphs and somewhat beyond. In contrast, it is shown here that the corresponding extensions are not possible in the case of the antiferromagnetic Ising model.
