Algebraic topology Homotopy: basic notions Concept
Pointed space
Summary
A pointed space is a topological space together with a chosen point, its base point. Maps of pointed spaces are continuous maps that send base point to base point. Many constructions of homotopy theory need a base point, such as the fundamental group, the loop space and the wedge sum.
