The main result of the note is that the square of the number of particles under the determinantal point process whose correlation kernel is an entire function of finite order has sub-Poissonian tails. The same result also holds in the symplectic Pfaffian case. As a corollary, sub-Poissonian estimates are also obtained for exponential moments of additive functionals over pairs of particles.","PeriodicalId":54736,"journal":{"name":"Moscow Mathematical Journal","volume":null,"pages":null},"PeriodicalIF":0.8,"publicationDate":"2023-12-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"139132799","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"数学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The overdamped Josephson junction is modeled by a family of differential equations on 2-torus depending on 3 parameters: $B$, $A$, $omega$. We study its rotation number $rho(B,A;omega)$ as a function of parameters. The three-dimensional phase-lock areas are the level sets $L_r:={rho=r}$ with non-empty interiors; they exist for $rinmathbb Z$ (Buchstaber, Karpov, Tertychnyi). For every fixed $omega>0$ and $rinmathbb Z$ the planar slice $L_rcap(mathbb R^2_{B,A}times{omega})$ is a garland of domains going vertically to infinity and separated by points; those separating points for which $Aneq0$ are called constrictions. In a joint paper by Yu.Bibilo and the author, it was shown that 1) at each constriction the rescaled abscissa $ell:=frac Bomega$ is equal to $rho$; 2) the family of constrictions with given $ellinmathbb Z$ is an analytic submanifold $Constr_ell$ in $(mathbb R^2_+)_{a,s}$, $a=omega^{-1}$, $s=frac Aomega$. Here we show that the limit points of $Constr_ell$ are $beta_{ell,k}=(0,s_{ell,k})$, where $s_{ell,k}>0$ are zeros of the Bessel function $J_ell(s)$, and it lands at them regularly. Known numerical pictures show that high components of $Int(L_r)$ look similar. In his paper with Bibilo, the author introduced a candidate to the self-similarity map between neighbor components: the Poincar'e map of the dynamical isomonodromic foliation governed by Painlev'e 3 equation. Whenever well-defined, it preserves $rho$. We show that the Poincar'e map is well-defined on a neighborhood of the plane ${ a=0}subsetmathbb R^2_{ell,a}times(mathbb R_+)_s$, and it sends $beta_{ell,k}$ to $beta_{ell,k+1}$ for integer $ell$.","PeriodicalId":54736,"journal":{"name":"Moscow Mathematical Journal","volume":null,"pages":null},"PeriodicalIF":0.8,"publicationDate":"2023-08-08","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"139351381","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"数学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

We show, using [14], that a smooth projective fibration f : X → Y between connected complex quasi-projective manifolds satisfies the equality κ ( X ) = κ ( X y ) + κ ( Y ) of Logarithmic Kodaira dimensions if its fibres X y admit a good minimal model. Without the last assumption, this was conjectured in [11]. Sev-eral cases are established in [13], which inspired the present text. Although the present results overlap with those of [13] in the projective case, the approach here is different, based on the rôle played by birationally isotrivial fibrations, special manifolds and the core map of Y introduced and constructed in [3].","PeriodicalId":54736,"journal":{"name":"Moscow Mathematical Journal","volume":null,"pages":null},"PeriodicalIF":0.8,"publicationDate":"2023-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"67827888","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"数学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
