The map T_j(x)=fracwidetilde C_j(x)-12^b_j is a bijective isometry Z_2→ Z_2, and widetilde C_j( Z_2)=1+2^b_j Z_2, j!widetilde C_j( Z_2)=j!+2^B_j Z_2. For r>B_j, one least period modulo 2^r visits every residue in j!+2^B_j Z/2^r Z exactly once. For r≤ B_j, there is one residue and the least row period is one.

Normalization is also an explicit implication. Using the existing definition E^(N,j)_Nn=j!C_N,j(n), the source proves that multiplication by j! commutes with every iterated difference. If the unnormalized difference has precision A, the normalized difference has precision A-v_p(j!). Precision is defined as x=0 hboxor v_p(x)≥ A, so zero and negative factorial-loss thresholds are handled correctly. For j<p, the loss is zero.

Normalization is also an explicit implication. Using the existing definition E^(N,j)_Nn=j!C_N,j(n), the source proves that multiplication by j! commutes with every iterated difference. If the unnormalized difference has precision A, the normalized difference has precision A-v_p(j!). Precision is defined as x=0 hboxor v_p(x)≥ A, so zero and negative factorial-loss thresholds are handled correctly. For j<p, the loss is zero.

Binomial coefficients vanish when their lower index exceeds n, which proves the interpolation claim. Equality of every point of the stencil proves equality of differences. …

Every nonempty L_v has a checked free and transitive action of ker J. The action is defined without choosing a base lift. Choosing one valid solved digit then gives an explicit bijection L_v≅ker J. In particular, for every positive modulus, o_x(v)=0 Longrightarrow # L_v=#ker J. These results permit composite q, the degenerate modulus q=1, and zero dimensions.

The result first follows from subgroup symmetry in the finite Hurwitz algebra. A second proof shows that the standard window operator preserves the finite space of sequences that are h periodic after their constant term.

Fix an odd prime p, a divisor mmid p-1, and put h=fracp-1m. The reduced standard window inverse is defined by ∑_q=0^n binommnmqe_q^(m,p) = δ_n0 in F_p. We prove that e_n+h^(m,p)=e_n^(m,p) (n≥1). The result first follows from subgroup symmetry in the finite Hurwitz algebra. A second proof shows that the standard window operator preserves the finite space of sequences that are h periodic after their constant term. The two arguments expose different parts of the same finite character structure.

Let B_m denote the Bernoulli numbers with B_1=-1/2. The identity obtained by substituting u=e^t-1 into log(1+u)/u is B_m=∑_r=0^m(-1)^rfracr!r+1 {m r}, where the braces are Stirling numbers of the second kind. Each 2r!/(r+1) is dyadically integral. Indeed, if s=v_2(r+1)>0, then r≥2^s-1 and v_2(r!)≥ v_2((2^s-1)!)=2^s-1-s≥ s-1. The last inequality is 2^s≥2s; the case s=0 is immediate. Consequently 2B_m∈ Z_2 (m≥0).

The definitions contain no product or inverse closure requirement. Since B commutes with U, derivatives of a bounded element remain bounded. Induction on r in the displayed product rule then proves closure under multiplication. The finite middle sums use the lower-order induction hypothesis, not the desired next-order conclusion.

Pascal's identity proves the first product rule, and induction proves the higher rule. The intermediate binomial coefficients binom pr vanish in characteristic p. For the inverse, solve row n using the coefficient of b_n, which is g_0=1: b_n=1_n-∑_r<nbinom nr b_r g_n-r. Subtract the first and pth product rules for b⋆ g=1. The assumed identity for g leaves (D^p b-Db)⋆ g=0. A second triangular induction shows that convolution with a sequence having constant coefficient 1 has trivial kernel.

There is a polynomial Q∈ R[U_1,…,U_d], with Q(0)=0, such that for every u∈ R^d, P(a+cu)=P(a)+c∑_j=1^d(∂_jP)(a)u_j+c^2Q(u). In particular, when R= Z and a,u,c are integral, subtracting the first two terms on the right from P(a+cu) gives a multiple of c^2.

Another representative has the form x'=x+p^Ls. Since L≥1, its Jacobian is the same modulo p. Dividing (1) by p^L shows that its residual digit is e'=e+Js, so it gives exactly the same quotient class. If t_0 solves (2), all its solutions are t_0+ker J, and no others. The finite cardinalities follow from rank-nullity. This also covers no variables, no equations, zero Jacobian and singular solutions. square

The original conjecture asks for a canonical finite obstruction packet whose vanishing is necessary and sufficient for a one-level lift in a finitely presented arithmetic seed system. For a fixed finite polynomial presentation, the paper now supplies the precise obstruction o_F,bar x=[r]∈ coker (J_F,bar x: F_p^d⟶ F_p^e), where r is the residual digit. We have proved independence from the chosen integer representative. Invariance under a change of equations or presentation requires more.

The latest continuation retains the exact Bernoulli undepletion factor e_r,q=frac1-2^2r-11-2^2r-14^q, q≥0. It is a dyadic unit, including e_r,0=1. Multiplication by this factor preserves the all-q error of the shifted Jacobi moment model. Consequently the actual model critical values satisfy, for every m≥25, v_2(Φ_r,m^act-Φ_r^act) ≥ L_m=8m-4s_2(m)-178, L_m⟶∞. The estimate includes every packet and controls motion of the critical point. There is no ceiling at the undepletion exponent 2r-25. For e…

To obtain the sharper displacement, begin with u∈ R^d. If u∈ p^nR^d, then Q(0)=0 and polynomial congruence give Q(u)∈ p^nR^d. For n<k, both C and pQ(u) are divisible by p^n+1. Equation~[source reference] therefore improves the divisibility of u by one digit. Induction gives u∈ p^kR^d. Thus b=a+p^s+1u satisfies [source reference], because s+1+k=r-s. Its normalized preconditioned value vanishes, and injectivity of A gives F(b)=0.

Because Θ(1+T)^b=b(1+T)^b, the binomial expansion of T^p=((1+T)-1)^p then proves stability of the divided generator T^p/p. For d=pq+r, 0≤ r<p, every weighted monomial has the exact factorization a_dT^d=(p^qa_d)(fracT^pp)^qT^r. The scalar p^qa_d is integral by the actual weight condition.

Now take the integral cyclic group ring R_N= Z[ Z/N Z], x=[1], x^N=1, and assume Nmid p(p-1). Thus (x^p-1)^p=1. Each genuine consecutive block ∏_i=0^p-1(x-(pb+i)) belongs to (p,x^p-1-1). This follows from the actual polynomial identity ∏_i∈ F_p(X-i)=X^p-X modulo p, not from a hypothesized valuation of the product.

The address-three source is G_4,3(t)=3(sinh t-sin t)/t^3. Addition identities give sinh t-sin t =2asinh(at)cosh(bt)+2bcosh(at)sinh(bt), cosh t-cos t=2sinh(at)sinh(bt). Consequently D_3(t):=G_4,3(t)F_2(t) =frac32(fraccoth(at)at +fraccoth(bt)bt). This expression is a power series: its two polar terms cancel because a^-2+b^-2=0. Its constant is one, only degrees divisible by four survive, and the Bernoulli expansion gives D_3(t)=∑_i≥0d_ifract^4i(4i)!, d_i=3(-frac14)^i frac2^4i+2B_4i+2(4i+2)(4i+1). …

ith-normalization-loss Take p=3, m=2, N=6, and j=3. The recurrence gives C_6,3(1)=-frac184, C_6,3(2)=frac7035460, C_6,3(2)-C_6,3(1)=frac64455. The last difference has 3-adic valuation zero. Here h=1, so at n=1 the order-one bound without factorial loss would require valuation at least one. The corrected normalized bound is sharp, since v_3(C_6,3(2)-C_6,3(1))=0=1-v_3(3!). Multiplication by 3! gives U_6,3(2)-U_6,3(1)=frac384455, v_3(U_6,3(2)-U_6,3(1))=1, consistent with the unnormalized theorem. T…

Square solved-block uniqueness. If m=e, every prescribed τ has exactly one root in the original ball: ∃! b∈ x+p^L Z_p^e+k: F(b)=0, free(b)=τ. Thus all valid integer parameter approximations and all lifting choices with the same target have the same endpoint. This does not assert uniqueness of the integer representatives in the tower.

Why a p-adic unit supplies one factor of p. Now let u∈ Z_p^×. The actual ring homomorphism π: Z_p⟶ F_p sends u to a nonzero unit. Fermat's finite-field theorem therefore gives π(u)^p-1=1, π(u^p-1-1)=0. Using the proved kernel identity kerπ=p Z_p, the source derives pmid u^p-1-1 inside Z_p. The conclusion is not supplied as an abstract certificate. It follows from the unit hypothesis and the standard residue-field construction.

Pascal's identity proves the first product rule, and induction proves the higher rule. The intermediate binomial coefficients binom pr vanish in characteristic p. For the inverse, solve row n using the coefficient of b_n, which is g_0=1: b_n=1_n-∑_r<nbinom nr b_r g_n-r. Subtract the first and pth product rules for b⋆ g=1. The assumed identity for g leaves (D^p b-Db)⋆ g=0. A second triangular induction shows that convolution with a sequence having constant coefficient 1 has trivial kernel.
