By changing the local parameter at infinity from $q=e^{2pi i tau}$ to the reciprocal of the elliptic modular $j$-function, we prove that all normalized extremal quasimodular forms of depth 1 have a hypergeometric series expression and that integrality is not affected by this change of parameters. Furthermore, by transforming these hypergeometric series expressions into a certain manageable form related to the Atkin(-like) polynomials and using the lemmas that appeared in the study of $p$-adic hypergeometric series by Dwork and Zudilin, the integrality problem can be reduced to the fact that a polynomial vanishes modulo a prime power, which we prove. We also prove that all extremal quasimodular forms of depth 1 with appropriate weight-dependent leading coefficients have integral Fourier coefficients by focusing on the hypergeometric expression of them.","PeriodicalId":14293,"journal":{"name":"International Journal of Number Theory","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2023-10-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"135918015","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"数学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

For $gammainoverline{mathbb{Q}}$, consider its irreducible polynomial in $mathbb{Z}[x]$, $F_{gamma}(x)=a_nx^n+dots+a_0$. Denote $e(gamma)=gcd(a_{n},a_{n-1},dots,a_1)$. Drungilas, Dubickas and Jankauskas show in a recent paper that $mathbb{Z}[gamma]cap mathbb{Q}={alphainmathbb{Q}mid {pmid v_p(alpha)<0}subseteq {pmid p|e(gamma)}}$. Given a number field $K$ and $gammainoverline{mathbb{Q}}$, we show that there is a subset $X(K,gamma)subseteq text{Spec}(mathcal{O}_K)$, for which $mathcal{O}_K[gamma]cap K={alphain Kmid {mathfrak{p}mid v_{mathfrak{p}}(alpha)<0}subseteq X(K,gamma)}$.
