Weak pullback mean random attractors for the stochastic convective Brinkman–Forchheimer equations and locally monotone stochastic partial differential equations [PDF]
Infinite Dimensional Analysis Quantum Probability and Related Topics, 2020 This work is concerned about the asymptotic behavior of the solutions of the two- and three-dimensional stochastic convective Brinkman–Forchheimer (SCBF) equations [Formula: see text] driven by white noise with nonlinear diffusion terms (for some ...

The pullbacks of principal coactions [PDF]
Documenta Mathematica, 2014 We prove that the class of principal coactions is closed under one-surjective pullbacks in an appropriate category of algebras equipped with left and right coactions. This allows us to handle cases of C^* -algebras lacking two different non-trivial ideals.

Homological Dimension of Pullbacks.
MATHEMATICA SCANDINAVICA, 1992 The main result of the paper is motivated by a result of \textit{E. Kirkman} and \textit{J. Kuzmanovich} for non-commutative rings [Pac. J. Math. 134, No. 1, 121-132 (1988; Zbl 0617.16014)] and states that if in a pullback diagram of commutative rings \[ \begin{matrix} A & @>i_ 1>> & A_ 1 \\ \downarrow && \downarrow \\ A_ 2 & \longrightarrow & A_ 0 ...

Pullback 𝒟-Attractor of Nonautonomous Three-Component Reversible Gray-Scott System on Unbounded Domains [PDF]
Abstract and Applied Analysis, 2013 The long time behavior of solutions of the nonautonomous three-components reversible Gray-Scott system defined on the entire space ℝn is studied when the external forcing terms are unbounded in a phase space.

Successful Placement of a Silicone Y-Stent Using the Pullback Technique Through a Self-Expandable Metallic Stent in a Case of Tuberculous Airway Stenosis. [PDF]
Respirol Case RepTuberculous tracheobronchial stenosis (TSTB) commonly involves the left main bronchus, and airway interventions, including silicone Y stent placement, are effective treatment options for patients with TSTB. In the hereby‐presented case, the silicone stent successfully stabilised the stenotic segments in the lower trachea and left main bronchus ...

Pullback attractors for weak solution to modified Kelvin-Voigt model
Evolution Equations & Control Theory, 2022 The paper is devoted to the investigation of the qualitative dynamics of weak solutions for the modified Kelvin-Voigt model on the base of the theory of pullback attractors for trajectory spaces.

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.

Pullback attractor for a nonautonomous parabolic Cahn-Hilliard phase-field system
AIMS Mathematics, 2023 Our aim in this paper is to study generalizations of the Caginalp phase-field system based on a thermomechanical theory involving two temperatures and a nonlinear coupling. In particular, we prove well-posedness results.

Pullback attractor for a nonlocal discrete nonlinear Schrödinger equation with delays
Electronic Journal of Qualitative Theory of Differential Equations, 2021 We consider a nonlocal discrete nonlinear Schrödinger equation with delays. We prove that the process associated with the non-autonomous model possesses a pullback attractor.
