Path connectedness of the regular part of non-collapsed RCD spaces
Path connectedness of the regular part of non-collapsed RCD spaces
Let be a non-collapsed space, and let denote its -regular set. Then the interior is path connected for all sufficiently small . Path-connectedness conjecture. The set
is path connected for all small . The authors suspect that the hypothesis used in the corresponding theorem is unnecessary; this conjecture asserts the resulting statement for every non-collapsed space.
