Overcategory: Products, Examples & Properties

In mathematics, an overcategory (also called a slice category) is a construction from category theory used in multiple contexts, such as with covering spaces (espace étalé). They were introduced as a mechanism for keeping track of data surrounding a fixed object X {\displaystyle X} in some category C {\displaystyle {\mathcal {C}}} . The dual notion is…
