More … WebLet H:X × I Y be a homotopy from f to g, and consider H∗E. This contains f∗E as the restriction of the bundle to X × {0} and g∗E as the restriction of the bundle to X × {1}, so it suffices to check that for any map h:X ×I Y, the restrictions of h∗E to X ×{0} and X ×{1} are isomorphic. First, let us consider this when h∗E is trivial.

WebFeb 7, 2024 · In the case of free homotopy classes you have to be a bit more careful: If the free homotopy class [ α] is represented by the conjugacy class of a hyperbolic element γ ∈ Γ then uniqueness follows from uniqueness of the geodesic axis A γ of γ (the unique γ -invariant geodesic in H n ). In the non-hyperbolic case the situation more subtle.
WebGradually, certain descriptions of the homotopy concept came to the front: constrained deformation (in which one or both endpoints are fixed) became favoured compared to free deformation. Although the latter is a more intuitive concept, the former will prove to be more interesting: it will allow for the introduction of a group structure. http://www.homepages.ucl.ac.uk/~ucahjde/tg/html/pi1-02.html
WebA free homotopy of loopsis a continuous map \(H\colon [0,1]\times[0,1]\to X\) such that \(\gamma_s(t):=H(s,t)\) is a loop for each fixed \(s\in[0,1]\), that is \(H(s,0)=H(s,1)\) for all \(s\in[0,1]\). Figure 1. In this figure, we see the …
WebThe homotopy class of this map completely characterises the bundle, and the process is in fact reversible. Given such a clutching function, one can construct a unique bundle over the suspension.
