Roughly … Webconnected, locally path connected and semi-locally simply-connected, for any subgroup Hof ˇ 1pX;x 0q, there is a covering complex p: X H ÑX, such that the induced map p #: ˇ 1pX H;x HqÑGis an isomorphism onto H—G. This paper shall make arguments using CW complexes, and there-fore it is necessary to show that a connected CW complex satis ...

WebUsing this slice theorem, we further study local fundamental groups of a Ricci limit space. We can show that for any ϵ > 0 and x ∈ X, there exists r ϵ, depending on ϵ and x, so that any loop in B_r(x) is contractible in B_ϵ(x). In particular, X is semi-locally simply connected. WebConstructing locally path connected examples with countable indiscrete fundamental groups is much harder. In fact, I think it is an open question whether or not there exists a Peano continuum with finite, indiscrete fundamental group.

WebIn general such a map $E\to E'$ is not itself a covering space, although this is true in the good case, i.e. when $X$ is connected and locally path-connected and semi-locally simply connected.
