WebNov 26, 2024 · The way I see it is that often when Physicists talk about diffeomorphisms they really just mean a coordinate transformation. However as far as I'm aware, when considering diffeomorphisms you're looking at how tensors change under a pushforward and a coordinate transformation. E.g. for a tensor, we apply a pushforward to the …

WebLet Symp(X) be the group of symplectomorphisms on a symplectic 4-manifold X. 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. WebDIFFEOMORPHISMS BY RUFUS BOWEN 1. Introduction. We shall study the distribution of periodic points for a class of diffeomorphisms defined by Smale [16, ?1.6]. We recall some of the definitions.

We obtain a dichotomy for C^ {1} -generic, volume-preserving diffeomorphisms: either all the Lyapunov exponents of almost every point vanish or the volume is ergodic and non-uniformly Anosov (i.e. nonuniformly hyperbolic and the splitting into stable and unstable spaces is dominated).

WebFeb 24, 2024 · Yes diffeomorphisms are immersions, but it's not clear to me why it should follow from the immersion case. A priori it seems that any perturbation of s could yield immersions which are not diffeomorphisms. In particular, these perturbations could kill surjectivity or injectivity. – D.
