Simple connectivity of limits of universal covers of RCD spaces
Simple connectivity of limits of universal covers of RCD spaces
Let be a sequence of spaces, and let be their universal covers. Assume that these universal covers converge in the pointed measured Gromov–Hausdorff sense to an space . Universal-cover limit conjecture. The limit space is simply connected. The question concerns stability of simple connectivity, or equivalently of the universal-cover structure, under pointed measured Gromov–Hausdorff limits; the source states it as an open problem.
