广义一致超图范畴中的内射壳与投射覆盖
Injectives Hulls and Projective Covers in Categories of Generalized Uniform Hypergraphs
摘要:
在广义一致超图范畴中构造了内射壳和投射覆盖,推广了箭图范畴和无向图范畴中的构造。虽然这些结构不是函子的,但它们是“子函子的”,这意味着它们是函子内射和投射加细的子分支。
英文摘要:
We construct injective hulls and projective covers in categories of generalized uniform hypergraphs which generalizes the constructions in the category of quivers and the category of undirected graphs. While the constructions are not functorial, they are "sub-functorial", meaning they are subobjects of functorial injective and projective refinements.
