I ask that Counting multiples in short intervals be recovered. I will provide an answer that is an enhancement of Lucia's comment as well as motivation for the question. It is part of my exploration of a combinatorial approach in number theory. (GRP20200411)
I would like to add as undelete-request On variants of the abc conjecture in terms of Lehmer means that was automatically deleted yesterday. If possible, I think that it is an interesting question about the abc conjecture. Many thanks.
