1 IUT III Go Yamashita RIMS, Kyoto 11/Dec/2015 at Oxford The author expresses his sincere gratitude to RIMS secretariat for typesetting his hand-written manuscript. 1 / 56
2 In short, in IUT II, we performed Galois evaluation theta fct theta values env labels gau labels (MF -objects (filtered φ-modules) Galois rep ns) 2 / 56
3 Two Problems 1. Unlike theta fcts, theta values DO NOT admit a multiradial alg m in a NAIVE way. 2. We need ADDITIVE str. for (log-) height fcts. µ log 3 / 56
4 On 1. Gal. eval. theta fcts theta values admit multirad. alg m ( cf. [IUT II, Prop 3.4(i)] ) ( constant monoids F ) l requires cycl. rig. via LCFT (cf. [IUT II, Prop 3.4(ii), Cor 3.7(ii), Rem (ii)]) 4 / 56
5 Recall cycl. rig. via LCFT uses O = (unit portion) (value gp portion) O core O theta values We DO NOT share it in both sides of Θ-link! {q j2 } j q DO NOT admit a multirad. alg m in a NAIVE way. 5 / 56
6 cf. use only µ-portion O µ 0 O µ cycl. rig. via mono-theta env. cycl. rig. via Ẑ Q >0 = {1} µ do not interfere core µ 0 7 admit a multirad. alg m 6 / 56
7 To overcome these problems, use log link! & allowing mild indet s non-interference etc. (later) 7 / 56
8 want to see alien ring str. O µ Θ-link log-link eye Note F ± l -symm. isom s are compatible w/ log-links can pull-back Ψ gau via log-link 8 / 56
9 However, O µ Θ log log Θ is highly non-commutative (cf. log(a N ) (log a) N ) cannot see from the right log 9 / 56
10 We consider the infinite chain of log-links log log log log this is invariant by one shift! 10 / 56
11 Important Fact k/q p fin. log O k log O k 1 2p log O k log shell = I k the domain & codomain of log are contained in the log-shell upper semi-compatibility (Note also: log-shells are rigid) 11 / 56
12 Besides theta values, we need another thing : we need NF (:= number field) to convert -line bdles into -line bdles and vice versa. 12 / 56
13 -line bdles def d in terms of torsors -line bdles def d in terms of fractional ideals natural cat. equiv. in a scheme theory 13 / 56
14 -line bdles def d only in terms of -str s admits precise log-kummer corr. But, difficult to compute log-volumes -line bdles def d by both of & -str s only admits upper semi-compatible log-kummer corr. But, suited to explicit estimates 14 / 56
15 We also include NFs as data (an NF) j v Q log(o ) theta values NFs } story goes in a parallel way in some sense ( of course essential difference cf. [IUT III, Rem 2.3.2, 2.3.3] ) 15 / 56
16 To obtain the final multirad. alg m: Frob.-like data assoc. to F-prime-strips Kummer theory étale-like data assoc. to D-prime-strips arith.-hol. forget arith. hol. str. mono-an. data assoc. to D -prime-strips 16 / 56

21 ( G v O ) k Kummer ( G v O k ( G v )) unlike the case of O k, Ẑ - indet. occurs container is invariant under this Ẑ -indet. OK cycl. rig. µ(g v ) µ(o k ) via LCFT? does not hold. now, we cannot use O k. use only O k 21 / 56
22 We want to protect value gp portion global real d portion from this Ẑ - indet! sharing O µ O µ w/ int. str. (Ind 2) Θ horizontal indet. 22 / 56
23 value gp portion O mono-theta cycl. rig. (unlike LCFT cycl. rig.) only µ is involved shared O µ O µ 0 core 0 µ µ NF portion Ẑ Q >0 = {1} cycl. rig. do not obstruct each others multirad. (on the function level) 23 / 56
24 Note also mono-theta cycl. rig. is compat. w/ prof. top. F ± l - sym. (conj. synchro.) log F ± l - sym. is compat. w/ log-links can pull-back coric (diagonal) obj. via log-links later LGP monoid (Logarithmic Gaussian Procession) 24 / 56

27 Note also µ log (log p (A)) = µ log (A) if A bij log p (A) compatibility of log-volumes ( w/ log-links ) do not need to care about how many times log. s are applied. 27 / 56
28 In the Archimedean case, we use a system (cf. [IUT III, Rem 4.8.2(v)]) & { O /µ N O /µ N } µ N is killed in O /µ N & constructions (of log-links, ) & start from O /µ N s, not O (cf. [IUT III, Def 1.1(iii)]) we put weight N on O /µ N for the log-volumes (cf. [IUT III, Rem.1.2.1(i)]) 28 / 56
29 NF portion as well, consider the actions of (F mod ) j after (Kummer) (log) n (n 0) By F mod v O v = µ No new action appears in the interation of log. s No interference 29 / 56
