Perinormality in pullbacks [PDF]

open access: yesJournal of Commutative Algebra, 2019
We further develop the notion of perinormality from our last paper, showing that it is preserved by many pullback constructions. In doing so, we introduce the concepts of relative perinormality and fragility for ring extensions.

Entropy rigidity for cusped Hitchin representations

open access: yesJournal of Topology, Volume 19, Issue 1, March 2026.
Abstract We establish an entropy rigidity theorem for Hitchin representations of geometrically finite Fuchsian groups which generalizes a theorem of Potrie and Sambarino for Hitchin representations of closed surface groups. In the process, we introduce the class of (1,1,2)‐hypertransverse groups and show for such a group that the Hausdorff dimension of

Asymptotic behavior of pullback attractors for non-autonomous micropolar fluid flows in 2D unbounded domains

open access: yesElectronic Journal of Differential Equations, 2018
In this article, we investigate the pullback asymptotic behavior of solutions for a non-autonomous micropolar fluid flows in 2D unbounded channel-like domains. First, applying the technique of truncation functions, decomposition of spatial domain, and

Stability of random attractors for non-autonomous stochastic $ p $-Laplacian lattice equations with random viscosity

open access: yesAIMS Mathematics
In this paper, we investigate the stability of pullback random attractors for non-autonomous stochastic $ p $-Laplacian lattice systems, which are influenced by random viscosity and multiplicative white noise. Under appropriate conditions, we first prove

Pullback attractor for a dynamic boundary non-autonomous problem with Infinite delay [PDF]

open access: yes, 2018
In this work we prove the existence of solution for a p-Laplacian non-autonomous problem with dynamic boundary and infinite delay. We ensure the existence of pullback attractor for the multivalued process associated to the non-autonomous problem we are ...

Pullbacks of Hermitian Maass lifts [PDF]

open access: yesJournal of Number Theory, 2015
We consider pullbacks of hermitian Maass lifts of degree 2 to the diagonal matrices. By using the pullbacks, we give an explicit formura for central values of L-functions for GL(2)*GL(2).

A general approach to the linear stability of viscoelastic shear‐flows

open access: yesZAMM - Journal of Applied Mathematics and Mechanics / Zeitschrift für Angewandte Mathematik und Mechanik, Volume 106, Issue 2, February 2026.
Abstract The present work provides an in‐depth analysis of the linear stability theory of viscoelastic shear‐flows, based upon a constitutive equation of the fading memory type. The particular model considered herein was introduced by Kenneth Walters through the integration of classical rate‐type fluids in a convected frame (Walters 1962).

Pullback attractors for a class of semilinear nonclassical diffusion equations with delay

open access: yesElectronic Journal of Differential Equations, 2016
In this article, we analyze the existence of solutions for a nonclassical reaction-diffusion equation with critical nonlinearity, a time-dependent force with exponential growth and delayed force term, where the delay term can be entrained by a ...
