As … 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. " - Free homotopy

WebMay 29, 2015 · We also show that taking only the shortest orbit representatives in each conjugacy classes still yields Bowen's version of the measure of maximal entropy. These results are achieved by obtaining counting results on the growth rate of the number of periodic orbits inside a free homotopy class. 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. So if is a map classifying the G-bundle E, how does this map relate to the clutching function ? How does one go between one and the other?

It is a classical problem in symplectic topology to study the homotopy type of Symp(X) and to compare it with the group of all diffeomorphisms on X. This problem is closely related to the existence of symplectic structures on smooth families of 4-manifolds.
