When Are Maps Homotopic?
Homotopy of Maps Two Continuous Maps F, G: X→Y Are Homotopic If There Is a Continuous Homotopy H: X×[0,1]→Y Such That H(X,0)=F(X) and H(X,1)=G(X) for All X∈X...
How do you prove homotopic?
Let A be a convex subset of Rn, endowed with the subspace topology, and let X be any topological space. Then any two continuous maps f,g: X → A are homotopic. Let X, Y be two topological spaces, and let Map(X, Y ) be the set of all continuous maps from X to Y .
Are all constant maps homotopic?
So we have : 1)Every map X → Y is homotopic to some constant map. 2)Any two constant maps X → Y are homotopic. Since homotopy is an equivalence relation, these two facts together imply that any two maps X → Y are homotopic.
