Reciprocal sum of prime-prefix-free numbers shown to converge
Original: The reciprocal sum of the prime-prefix-free numbers converges [pdf]
A new paper proves that the sum of reciprocals of the prime-prefix-free numbers — integers that share no common prefix, digit by digit, with a prime — converges to a finite value. The result settles a question about a set whose sum of reciprocals was not obviously finite or infinite. Readers of a mathematics-focused discussion site are engaging with the short proof and debating the counting argument behind it.
Why now: A newly published proof resolves a number theory question, drawing attention from math enthusiasts.
