作为同伦类型模型的图解集合

Diagrammatic sets as a model of homotopy types

Clémence Chanavat, Amar Hadzihasanovic

AI总结:

该研究引入源于组合拓扑与高维图重写的图解集合,构建其上余纤维生成的模型结构,证明其与单纯集经典模型结构的两个Quillen等价,且该结构关于Gray积是幺半的,为同伦类型提供新模型。

摘要:

图解集合(diagrammatic sets)是定义在一类丰富形状范畴上的预层,其定义的灵感来源于组合拓扑与高维图重写。这些形状包含有向单纯形、立方体与正opetope的代表元,并且在Gray积、join(并)、suspension(同纬)与对偶等运算下保持封闭。我们给出了图解集合上的一个余纤维生成的模型结构,以及它与单纯集合上经典模型结构之间的两个独立的Quillen等价。我们构造了生成余纤维与生成无环余纤维的显式集合,并证明该模型结构关于图解集合的Gray积是幺半的。

英文摘要:

Diagrammatic sets are presheaves on a rich category of shapes, whose definition is motivated by combinatorial topology and higher-dimensional diagram rewriting. These shapes include representatives of oriented simplices, cubes, and positive opetopes, and are stable under operations including Gray products, joins, suspensions, and duals. We exhibit a cofibrantly generated model structure on diagrammatic sets, as well as two separate Quillen equivalences with the classical model structure on simplicial sets. We construct explicit sets of generating cofibrations and acyclic cofibrations, and prove that the model structure is monoidal with the Gray product of diagrammatic sets.
