S2b-2 / S2b-3: the proof notes, §6 "Local shapes" and "Scaling", for the
entries of one class block, on its own disc and on the other discs (n = p - 1).
Local shape of seriesPart / nearProd on the disc b for a = ⟨b, i⟩, c = ⟨b, k⟩
(κ(u) = (unit) (1 + O(p u)), κ(0) ≡ w_b):
- low (
1 ≤ b ≤ p-5,nearSet = {0,…,4}):p^{4+i+k} u^{i+k} r_L(u) κ(u); - high (
p-4 ≤ b,nearSet = {0,…,3}):p^{4+i+k} u^{i+k} r_H(u) κ(u); - zero (
b = 0,nearSet = {1,…,4}):p^{1+i+k} u^{i+k} r_0(u) κ(u). With thep^{-|near|}ofdiscLocaland thep^{-2}of Corollary 2 the power isp^{c_b+i+k}. Modulo one more power ofpthe local functional isV⁰(the2rpmoments are≡ 0, a moment of valuation-1needs degree≥ 2p-1, and each extra power ofpinκraises the degree by at most one). Expected unit weight (hint only, not checked; not needed in the statement):w_b = (-b)·∏_{b'≠b}(b'-b)^{2m_{b'}}·∏_{1≤i'≤p-1, i'≠b}(i'-b)^4 / ∏_{j∈[1,5(p-1)], j≢b}(j-b)forb ≠ 0, and the same without the factor(-b)forb = 0.
Proof (files in Disc/): Factor writes dissectNum on the disc d as p^E u^E R(u) with R
scaled (u^e-coefficient of valuation ≥ e) and R(0) a unit, so the coefficient of u^e in
seriesPart vanishes for e < E and has valuation ≥ e (Core). Core.VG_locValue_scaled is
Lemma 3 for such numerators (LocValue, Bernoulli: von Staudt). Other disc: E - |near| - 2 ≥ 2.
Own disc: w_b = K(0) for K = R_b / farProd; subtracting p^E K(0) u^E leaves a numerator
vanishing to order E + 1, and V_{rp}(u^E) ≡ V⁰(u^E) mod p (degree E ≤ |near| + p - 2).
Exponent bookkeeping on the own disc b, and blockMoment as V⁰(u^E / nearProd).
The own-disc estimate, abstractly: P has u^e-coefficients of valuation ≥ e, vanishing
below E, with u^E-coefficient p^E K₀.
S2b-2 (own disc). For two vectors of the same class b, the disc-b local term is
p^{c_b+i+k} · w_b · V⁰(u^{i+k} r_type) modulo p^{c_b+i+k+1}, with p-unit weights w_b
depending only on the class.
S2b-3 (other discs). For two vectors of the same class b, every other disc d ≠ b
contributes with excess ≥ 1: by Lemma 3 (local integrality; the degree condition holds since at
most 10 near zeros occur and 10 ≤ |near| + 2p - 2) the term has valuation
≥ c_d + 2 m_d ≥ 2 ≥ ρ_a + ρ_c + 1.
