我们考虑一个多参数模型,随机构建单纯形复杂的随机集团复杂和Linial-Meshulam随机k维复杂之间的插值。与这些模型不同的是,多参数复合体同时在许多维度上表现出非平凡的同源性。我们建立上限和下限阈值的外观在每个维度上的非平凡上同调,并在临界状态下的行为特征。
We consider a multi-parameter model for randomly constructing simplicial complexes that interpolates between random clique complexes and Linial–Meshulam random k-dimensional complexes. Unlike these models, multi-parameter complexes exhibit nontrivial homology in numerous dimensions simultaneously. We establish upper and lower thresholds for the appearance of nontrivial cohomology in each dimension and characterize the behavior at criticality.
