Integral cokernel receipt

Exact statement

A word ww has an integral periodic lift exactly when [aw]=0[a_w]=0 in Z/(2k−3s(w))\mathbb Z/(2^k-3^{s(w)}); every nonempty word has a unique 2-adic lift because the coefficient 2k−3s(w)2^k-3^{s(w)} is odd and nonzero.

Context

Parity words are exact affine charts. Their seams, response quotients, integral cokernels, and 2-adic inverse limits show precisely where finite compatibility differs from membership in the ordinary nonnegative integers.

Proof or evidence

The receipt is the cokernel class of multiplication by 2k−3s2^k-3^s; integral and 2-adic doctrines are checked separately.

Verification notes

The affine word, residue-cylinder, seam, response, integral, positive, 2-adic, selector, rotation, and fixed-weight arguments were reconstructed. An independent implementation checked 131,070 parity words, 98,304 seams, 98,305 swaps, 8,800 primitive necklaces, and all selectors through depth four, including the 001 and all-ones hostile examples.

Limitations

  • An integral lift is positive only with the additional sign conditions.

Open work

Keep integral, positive, and 2-adic acceptance as separate quotients.
