In particular, for any geometrically irreducible $overline{mathbb{Q}}_p$-local system on a smooth variety over a number field the associated projective representation of the fundamental group automatically satisfies the assumptions of the relative Fontaine-Mazur conjecture. The proof uses $p$-adic Simpson and Riemann-Hilbert correspondences of Diao-Lan-Liu-Zhu and the Sen operator on the decompletions of those developed by Shimizu. Along the way, we observe that a $p$-adic local system on a smooth geometrically connected algebraic variety over $K$ is Hodge-Tate if its stalk at one closed point is a Hodge-Tate Galois representation. Moreover, we prove a version of the main theorem for local systems with arbitrary geometric monodromy, which allows us to conclude that the Galois action on the pro-algebraic completion of the fundamental group is de Rham.","PeriodicalId":11447,"journal":{"name":"Duke Mathematical Journal","volume":" ","pages":""},"PeriodicalIF":2.5,"publicationDate":"2020-12-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"45038339","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"数学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

We show that as $epsilon to 0$, at zero temperature the correlation length scales as $e^{epsilon^{-4/3+o(1)}}$ (and our upper bound applies for all positive temperatures).

Such a class can be evaluated at the real quadratic irrationalities in Hp, which are referred to as “RM points”. Rigid meromorphic cocycles can be envisaged as the real quadratic counterparts of Borcherds’ singular theta li‰s: their zeroes and poles are contained in a €nite union of Γ-orbits of RM points, and their RM values are conjectured to lie in ring class €elds of real quadratic €elds. ‘ese RM values enjoy striking parallels with the CM values of modular functions on SL2(Z)H: in particular they seem to factor just like the di‚erences of classical singular moduli, as described by Gross and Zagier.

A result of this type could be expected by analogy with the classical Pila-Wilkie counting theorem in the archimean situation. \u0000Some non-archimedean analogs of this type have been developed in the work of Cluckers-Comte-Loeser for the field ${mathbb{Q}}_p$, but the situation in ${mathbb{C}}(!(t)!)$ appears to be significantly different. We prove that the set of polynomial curves of a fixed degree $r$ on the transcendental part of a subanalytic set over ${mathbb{C}}(!(t)!)$ is automatically finite, but give examples showing that their number may grow arbitrarily quickly even for analytic sets. Thus no analog of the Pila-Wilkie theorem can be expected to hold for general analytic sets. On the other hand we show that if one restricts to varieties defined by Pfaffian or Noetherian functions, then the number grows at most polynomially in $r$, thus showing that the analog of Wilkie's conjecture does hold in this context.","PeriodicalId":11447,"journal":{"name":"Duke Mathematical Journal","volume":" ","pages":""},"PeriodicalIF":2.5,"publicationDate":"2020-09-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"47553123","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"数学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
