Corrigendum to: “Growth of Unbounded Subsets in Nilpotent Groups, Random Mapping Statistics, and Geometry of Group Laws”

open access: yesInternational Mathematics Research Notices, 2022
Abstract We fix Lemma 6.2 in our recent paper [1] and correct the constants derived from it, appearing in Theorems 1.1, 1.3, and 1.4 and Corollary 6.5.

On real analytic functions of unbounded type [PDF]

open access: yes, 2013
In this paper we prove several results on the existence of analytic functions on an infinite dimensional real Banach space which are bounded on some given collection of open sets and unbounded on others. In addition, we also obtain results on the density

On a generalized density point defined by families of sequences involving ideals [PDF]

open access: yesMathematica Bohemica
We introduce the notion of $\mathcal{I}_{(s)}$-density point corresponding to the family of unbounded and $\mathcal{I}$-monotonic increasing positive real sequences, where $\mathcal{I}$ is the ideal of subsets of the set of natural numbers.

Convolutions of sets with bounded VC-dimension are uniformly continuous

open access: yesDiscrete Analysis, 2021
Convolutions of sets with bounded VC-dimension are uniformly continuous, Discrete Analysis 2021:1, 25 pp. In recent years there has been a cross-fertilization between combinatorics and model theory, as a result of the realization that certain model ...

Adding Closed Unbounded Subsets of ω2 with Finite Forcing.

open access: yesNotre Dame J. Formal Log., 2005
An outline is given of the proof that the consistency of a κ⁺-Mahlo cardinal implies that of the statement that I[ω₂] does not include any stationary subsets of Cof(ω₁). An additional discussion of the techniques of this proof includes their use to obtain a model with no ω₂-Aronszajn tree and to add an ω₂-Souslin tree with finite conditions.

Functor of extension of $\Lambda$-isometric maps between central subsets of the unbounded Urysohn universal space

open access: yes, 2010
summary:The aim of the paper is to prove that in the unbounded Urysohn universal space $\mathbb U$ there is a functor of extension of $\Lambda $-isometric maps (i.e. dilations) between central subsets of $\mathbb U$ to $\Lambda $-isometric maps acting on

Random fixed point theorems for a random operator on an unbounded subset of a Banach space

open access: yesApplied Mathematics Letters, 2008
The authors obtain random fixed point theorems for nonexpansive random operators and claim to improve certain results of \textit{G.\,Isac} and \textit{S.\,Z.\thinspace Németh} [J.~Math.\ Anal.\ Appl.\ 314, No.\,2, 500--512 (2006; Zbl 1090.47041)] and \textit{J.--P.\thinspace Penot} [Proc.\ Am.\ Math.\ Soc.\ 131, No.\,8, 2371--2377 (2003; Zbl 1035.47043)

Lattice uniformities inducing unbounded convergence

open access: yes, 2022
A net $(x_\gamma)_{\gamma\in\Gamma}$ in a locally solid Riesz space $(X,\tau)$ is said to be unbounded $\tau$-convergent to $x$ if $|x_\gamma-x|\wedge u\mathop{\overset{\tau}{\longrightarrow}} 0$ for all $u\in X_+$.

On unbounded Bergman operators

open access: yes, 2003
This paper explores properties of the Bergman operator on unbounded open subsets of the plane. In addition to the characterization of the bounded commutant of such operators it proves the Berger–Shaw theorem and gives some general criteria under which ...
