WebA circle does retract onto a point, because a retract of a circle to a point on it is just a constant map r: S 1 → { p }. What you're really asking about is the fact that a circle doesn't deformation retract onto a point. A deformation retract would be a homotopy F: S 1 × I → S 1 taking the circle to one of its points, so to deformation ...

Let's simply say that there are many different kind of deformation retraction, one stronger than the other. The weaker form states that A ⊆ X is a (weak)deformation retract of X iff there's a map r: X → A such that r is both a left and right homotopy inverse to the inclusion map i: A → X (so A must be homotopy equivalent to X ). kentucky whitetail hunting lodgesWebAlgebraic Topology Problems Ethan Lake February 19, 2016 Problem 1.
