Cosmic Crystallography with a Pullback [PDF]
Physics Letters A, 1999 We present a modified version of the cosmic crystallography method, especially useful for testing closed models of negative spatial curvature. The images of clusters of galaxies in simulated catalogs are ``pulled back'' to the fundamental domain before ...

Pullback incremental attraction
Nonautonomous Dynamical Systems, 2014 A pullback incremental attraction, a nonautonomous version of incremental stability, is introduced for nonautonomous systems that may have unbounded limiting solutions.

Pullbacks and universal catenarity [PDF]
Publicacions Matemàtiques, 2008 This paper deals with the universal catenarity of a pullback construction ring. It seeks necessary and sufficient conditions for such a pullback to have the universal catenarity, improving some known results. Its main result leads to new examples of universally catenarian domains.

Formalized Mathematics, 2015 Summary The main purpose of this article is to introduce the categorical concept of pullback in Mizar. In the first part of this article we redefine homsets, monomorphisms, epimorpshisms and isomorphisms [7] within a free-object category [1] and it is shown there that ordinal numbers can be considered as categories.

Lax pullback complements and pullbacks of spans
Theory and Applications of Categories, 2018 Pullback complements were introduced by the second author [Partial products and pullback complements, Seminarberichte (Fernuniversität Hagen) 18, 199--216 (1983); see also \textit{R. Dyckhoff} and \textit{W. Tholen}, J. Pure Appl. Algebra 49, 103--116 (1987; Zbl 0659.18003)] and, since then, they were used, especially in theoretical computer science ...

Continuity of selected pullback attractors [PDF]
Partial Differential Equations and Applications, 2021 In this work we obtain theoretical results on continuity of selected pullback attractors and we apply them to reaction diffusion equations with dynamical boundary ...

Pullback attraction in H 0 1 $H_{0}^{1}$ for semilinear heat equation in expanding domains
Boundary Value Problems, 2020 In this article, we consider the pullback attraction in H 0 1 $H_{0}^{1}$ of pullback attractor for semilinear heat equation with domains expanding in time. Firstly, we establish higher-order integrability of difference about variational solutions; then,

Random Attractor for Stochastic Wave Equation with Arbitrary Exponent and Additive Noise on $\mathbb{R}^n$ [PDF]
, 2014 Asymptotic random dynamics of weak solutions for a damped stochastic wave equation with the nonlinearity of arbitrarily large exponent and the additive noise on $\mathbb{R}^n$ is investigated.
