  • Orders on Trees and Free Products of Left-ordered Groups
    • Authors: Dicks; Warren, Šunić, Zoran
      Pages: 335 - 347
      Abstract: We construct total orders on the vertex set of an oriented tree. The orders are based only on up-down counts at the interior vertices and the edges along the unique geodesic from a given vertex to another.As an application, we provide a short proof (modulo Bass–Serre theory) of Vinogradov’s result that the free product of left-orderable groups is left-orderable.

      Abstract: Let be a quasi-finite endomorphism of an algebraic variety  defined over a number field  and fix an initial point .

We show that the set satisfies a strong gap principle.

      Pages: 423 - 433
      Abstract: For a split semi-simple group scheme and a principal -bundle on a relative curve , we study a natural obstruction for the triviality of on the complement of a relatively ample Cartier divisor . We show, by constructing explicit examples, that the obstruction is nontrivial if is not simply connected, but it can be made to vanish by a faithfully flat base change, if is the spectrum of a dvr (and some other hypotheses). The vanishing of this obstruction is shown to be a sufficient condition for étale local triviality if is a smooth curve, and the singular locus of is finite over  .

  • The Spectral Radius Formula for Fourier–Stieltjes Algebras

      Pages: 269 - 275
      Abstract: In this short note we first extend the validity of the spectral radius formula, obtained by M. Anoussis and G. Gatzouras, for Fourier–Stieltjes algebras. The second part is devoted to showing that, for the measure algebra on any locally compact non-discrete Abelian group, there are no non-trivial constraints among three quantities: the norm, the spectral radius, and the supremum of the Fourier–Stieltjes transform, even if we restrict our attention to measures with all convolution powers singular with respect to the Haar measure.

      Pages: 304 - 317
      Abstract: Let be a variable exponent function satisfying the globally log-Hölder continuous condition. In this paper, we obtain the boundedness of paraproduct operators on variable Hardy spaces , where . As an application, we show that non-convolution type Calderón–Zygmund operators are bounded on if and only if , where and is the regular exponent of kernel of . Our approach relies on the discrete version of Calderón’s reproducing formula, discrete Littlewood–Paley–Stein theory, almost orthogonal estimates, and variable exponents analysis techniques. These results still hold for variable Hardy space on spaces of homogeneous type by using our methods.

  • Dense Orderings in the Space of Left-orderings of a Group
    • Authors: Clay; Adam, Reimer, Tessa
      Pages: 393 - 404
      Abstract: Every left-invariant ordering of a group is either discrete, meaning there is a least element greater than the identity, or dense. Corresponding to this dichotomy, the spaces of left, Conradian, and bi-orderings of a group are naturally partitioned into two subsets. This note investigates the structure of this partition, specifically the set of dense orderings of a group and its closure within the space of orderings. We show that for bi-orderable groups, this closure will always contain the space of Conradian orderings—and often much more. In particular, the closure of the set of dense orderings of the free group is the entire space of left-orderings.

  • Stability of Almost Periodic Nicholson’s Blowflies Model Involving Patch
           Structure and Mortality Terms
    • Authors: Huang; Chuangxia, Long, Xin, Huang, Lihong, Fu, Si
      Pages: 405 - 422
      Abstract: Taking into account the effects of patch structure and nonlinear density-dependent mortality terms, we explore a class of almost periodic Nicholson’s blowflies model in this paper. Employing the Lyapunov function method and differential inequality technique, some novel assertions are developed to guarantee the existence and exponential stability of positive almost periodic solutions for the addressed model, which generalize and refine the corresponding results in some recently published literatures. Particularly, an example and its numerical simulations are arranged to support the proposed approach.

  • Assouad Spectrum Thresholds for Some Random Constructions
    • Authors: Troscheit; Sascha
      Pages: 434 - 453
      Abstract: The Assouad dimension of a metric space determines its extremal scaling properties. The derived notion of the Assouad spectrum fixes relative scales by a scaling function to obtain interpolation behaviour between the quasi-Assouad and the box-counting dimensions. While the quasi-Assouad and Assouad dimensions often coincide, they generally differ in random constructions. In this paper we consider a generalised Assouad spectrum that interpolates between the quasi-Assouad and the Assouad dimension. For common models of random fractal sets, we obtain a dichotomy of its behaviour by finding a threshold function where the quasi-Assouad behaviour transitions to the Assouad dimension. This threshold can be considered a phase transition, and we compute the threshold for the Gromov boundary of Galton–Watson trees and one-variable random self-similar and self-affine constructions. We describe how the stochastically self-similar model can be derived from the Galton–Watson tree result.
