Finite-rank conjecture for profinite groups with finite-rank centralizers
Finite-rank conjecture for profinite groups with finite-rank centralizers
Let be a profinite group in which the centralizer of every nontrivial element has finite rank. Suppose that is not a pro- group.
Finite-rank conjecture. Then has finite rank.
This conjecture extends the preceding result for profinite groups whose nontrivial-element centralizers are virtually procyclic. It asks whether the same finite-rank conclusion remains valid under the weaker assumption that all such centralizers merely have finite rank.
