comment Is there any large diffeomorphisms of $S^{n}\times S^1 $like Torus?
Discontinuous in the sense, it can't be deformed continuously. I think the definition of large diffeomorphism is that you can't achieve them by infinitesimal transformations, like $x \rightarrow -x$ can't be achieved by continuos transformations.

Okay I think I got my answer, I shall close this section once I read the document.

@Fabian : As far as I know, the definition is bit sloppy, but we physicists live with it.

comment Path integrals using Fourier transformation
@Fabian : Well I don't know if there is a rigorous definition of $DX(t)$ because it appears in path integrals, accounting for all the paths that have the above mentioned periodicity. One way to think of it is in time-slice method of evaluation of feynmann path integrals is $DX(t) = lim_{n\rightarrow \infty} \prod_n dq_n$ .
