Conjecture I on tameness of infinitely punctured planes
Conjecture I on tameness of infinitely punctured planes
Let denote the class of closed discrete subsets of , and let . An automorphism has infinite order if no positive power of is the identity. The quotient is formed by the cyclic group generated by .
Conjecture I. If there exists an automorphism of infinite order such that the quotient space has infinitely many punctures, then is not tame.
The conjecture is motivated by the preceding theorem, which shows that tameness would force arbitrarily many points of to occur in every prescribed small disk under the same quotient hypothesis. The source provides no resolution, so the conjecture remains open.
