Space‐Time Modeling and Numerical Simulations of Non‐Newtonian Fluids Using Internal Variables

International Journal for Numerical Methods in Fluids, Volume 97, Issue 12, Page 1457-1481, December 2025.
Based on Hamilton's principle, the study focuses on a novel strategy for the modeling of non‐Newtonian fluids with the help of internal variables. Here, the viscosity evolves locally in space and time. Three configurations are numerically implemented, namely channel flow, a benchmark, and a lid‐driven cavity.

On the principle of linearized stability for quasilinear evolution equations in time‐weighted spaces

Mathematische Nachrichten, Volume 298, Issue 12, Page 3939-3959, December 2025.
Abstract Quasilinear (and semilinear) parabolic problems of the form v′=A(v)v+f(v)$v^{\prime }=A(v)v+f(v)$ with strict inclusion dom(f)⊊dom(A)$\mathrm{dom}(f)\subsetneq \mathrm{dom}(A)$ of the domains of the function v↦f(v)$v\mapsto f(v)$ and the quasilinear part v↦A(v)$v\mapsto A(v)$ are considered in the framework of time‐weighted function spaces ...

Structural analysis of co‐sputtered Cu–Nb and Cu–Pd textured thin films

Journal of Applied Crystallography, Volume 58, Issue 6, Page 1995-2005, December 2025.
This study investigates the structural evolution of co‐sputtered Cu‐based thin films with varying concentrations of Nb and Pd, using X‐ray diffraction, scanning electron microscopy and energy‐dispersive X‐ray spectroscopy. A random intercalation model is proposed to explain the observed structural trends and is applicable to other co‐deposited thin ...

Para-Associative Algebroids

Mathematics
We introduce para-associative algebroids as vector bundles whose sections form a ternary algebra with a generalised form of associativity. We show that a necessary and sufficient condition for local triviality is the existence of a differential ...

Čtyři empirické principy Ehrenfrieda Walthera von Tschirnhause

Filosofický časopis, 2022
This historically oriented study is dedicated to the German naturalist, mathematician and philosopher Ehrenfried Walther von Tschirnhaus (1651–1708) and aims to introduce his main philosophical-logical work, Medicina mentis. After a biographical overview,

Steinberg–Leibniz algebras and superalgebras

Journal of Algebra, 2005
The Steinberg Lie algebra \({\mathfrak s}{\mathfrak t}(n,A)\), \(n\geq 3\), over a unital associative algebra \(A\) is the universal central extension of the matrix Lie algebra \({\mathfrak s}{\mathfrak l}(n,A)\), and the Leibniz algebra \({\mathfrak s}{\mathfrak t}{\mathfrak l}(n,A)\) has a similar property in the category of Leibniz algebras.

Solvable Leibniz algebras with NFn⊕ Fm1$\begin{array}{} F_{m}^{1} \end{array} $ nilradical

Open Mathematics, 2017
All finite-dimensional solvable Leibniz algebras L, having N = NFn⊕ Fm1$\begin{array}{} F_{m}^{1} \end{array} $ as the nilradical and the dimension of L equal to n+m+3 (the maximal dimension) are described.

A rigid Leibniz algebra with non-trivial HL^2

, 2019
In this article, we generalize Richardson's example of a rigid Lie algebra with non-trivial $H^2$ to the Leibniz setting. Namely, we consider the hemisemidirect product ${\mathfrak h}$ of a semidirect product Lie algebra $M_k\rtimes{\mathfrak g}$ of a ...

Almost-reductive and almost-algebraic Leibniz algebra

International Electronic Journal of Algebra
This paper examines whether the concept of an almost-algebraic Lie algebra developed by Auslander and Brezin in [J. Algebra, 8(1968), 295-313] can be introduced for Leibniz algebras. Two possible analogues are considered: almost-reductive and almost-algebraic Leibniz algebras.
