👉 Ascendible is a category of objects in mathematics, specifically in topology and algebraic geometry. It is a type of object that can be "lifted" (or "lifted up") to another object of a given category. In topology, an object X is said to be "ascendible" if there exists a continuous function f from X onto some topological space Y such that the inverse image under f of any closed subset C of Y is also a closed subset of X
