Claim. P. Pollack and L. Troupe, Sums of proper divisors follow the Erdős--Kac law, Proc. Amer. Math. Soc. 151 (2023), no. 3, 977--988, Theorem 1: for each fixed real , as ,
(card).
Derived as the card states, not stated as a theorem in the paper: for every the target has density zero by the classical Erdős--Kac theorem, and Theorem 1, with replaced by for all but of the , gives it a density-zero preimage, the assertion of Problem 955 for that target.
Covers. For every , the target ; the general assertion stays open.

Acceptance. Refereed: Proceedings of the American Mathematical Society, a journal. The site's commentary does not credit the result, and the site labels the problem OPEN, so no curator acceptance is listed.
