Existence of steady solutions for a model for micropolar electrorheological fluid flows with not globally --Hölder continuous shear exponent

Alex Kaltenbach, Michael Růžička

In this paper, we study the existence of weak solutions to a steady system that describes the motion of a micropolar electrorheological fluid. The constitutive relations for the st…

Existence of steady solutions for a general model for micropolar electrorheological fluid flows

Alex Kaltenbach, Michael Růžička

In this paper we study the existence of solutions to a steady system that describes the motion of a micropolar electrorheological fluid. The constitutive relations for the stress t…

On the existence of weak solutions for a family of unsteady rotational Smagorinsky models

Luigi C. Berselli, Alex Kaltenbach, Roger Lewandowski +1

In this paper we show that the rotational Smagorinsky model for turbulent flows, can be put, for a wide range of parameters in the setting of Bochner pseudo-monotone evolution equa…

Variable exponent Bochner-Lebesgue spaces with symmetric gradient structure

A. Kaltenbach, R. Růžička

We introduce function spaces for the treatment of non-linear parabolic equations with variable -Hölder continuous exponents, which only incorporate information of the symmetr…

Analysis of fully discrete, quasi non-conforming approximations of evolution equations and applications

Luigi C. Berselli, Alex Kaltenbach, Michael Ruzicka

In this paper we consider fully discrete approximations of abstract evolution equations, by means of a quasi non-conforming spatial approximation and finite differences in time (Ro…

Note on the existence theory for pseudo-monotone evolution problems

Alex Kaltenbach, Michael Růžička

In this note we develop a framework which allows to prove an existence result for non-linear evolution problems involving time-dependent, pseudo-monotone operators. This abstract e…
