Existing theoretical stabilization results for linear, hyperbolic multi-dimensional problems are extended to the discretized multi-dimensional problems. In contrast to existing theoretical and numerical analysis in the spatially one-dimensional case

Multi-component Baer-Nunziato-type models for isothermal and isentropic fluids are investigated. These are given by balance equations for volume fractions, density and momentum for each component accounting for the relaxation to equilibrium by means

The ultra-relativistic Euler equations for an ideal gas are described in terms of the pressure, the spatial part of the dimensionless four-velocity and the particle density. Radially symmetric solutions of these equations are studied in two and three

The interest in boundary feedback control of multi-dimensional hyperbolic systems is increasing. In the present work we want to compare some of the recent results available in the literature.

Recently the barotropic two fluid model belonging to the class of \emph{symmetric hyperbolic thermodynamically compatible} (SHTC) systems was studied in detail in \cite{Thein2022}. There the question was raised whether the dissipative structure intro

The influence of chaotic capillary waves on the time-averaged shape of a liquid volume is studied experimentally and theoretically. In that context, a liquid film containing a stable hole is subjected to Faraday waves. The waves induce a shrinkage of

Abstract Collateral is a significant challenge for small and medium enterprises (SMEs) in acquiring formal credit. Bank market concentration can cause to increase collateral demand through enhancing bank market power. This study explores the relation

As recent trends in manufacturing engineering disciplines show a clear development in the sustainable as well as economically efficient design of forming processes, monitoring techniques have been gaining in relevance. In terms of monitoring of produ

We are interested in the feedback stabilization of general linear multi-dimensional first order hyperbolic systems in $\R^d$. Using a Lyapunov function with a suited weight function dpending on the system under consideration we show stabilization in
