摘要
基于超图范畴积引入了一类Hom-构造,并证明了范畴积运算在相应的Hom-构造下的相互作用良好.接着讨论了该Hom-构造与丘成桐先生等定义的超图同态同伦的关系,从拓扑的角度给出了丘成桐等人定义的超图同态同伦的必要条件.
Abstract
A Hom-construction associated to the categorical product of hypergraphs is introduced.It's shown that the categorical product operation interacts well with corresponding Hom-constructions.Then the relations between Hom-construction and the homotopy of hypergraph homomorphisms defined by Shing-Tung Yau et al are studied.A necessary condition of the homotopy of hypergraph homomorphisms from the view of topology is provided.
