A class of symmetric-hyperbolic PDEs modelling fluid and solid continua*** [PDF]

ESAIM: Proceedings and Surveys
We generalize a new symmetric-hyperbolic system of PDEs proposed in [ESAIM:M2AN 55 (2021) 807-831] for Maxwell fluids to a class of systems that define unequivocally multi-dimensional visco-elastic flows. Precisely, within a general setting for continuum

A new look at the controllability cost of linear evolution systems with a long gaze at localized data

Comptes Rendus. Mathématique
We revisit the classical issue of the controllability/observability cost of linear first order evolution systems, starting with ODEs, before turning to some linear first order evolution PDEs in several space dimensions, including hyperbolic systems and ...

Exact solutions in ideal chromatography via differential constraints method

Atti della Accademia Peloritana dei Pericolanti : Classe di Scienze Fisiche, Matematiche e Naturali, 2015
A differential constraints analysis is worked out for a quasilinear hyperbolic system of first order PDEs written in terms of Riemann invariants which models multicomponent ideal chromatography.

An Analysis of a Family of Difference Schemes for Solving Hyperbolic Partial Differential Equations

Mathematics
Partial differential equations are an integral part of modern scientific development. Hyperbolic partial differential equations are encountered in many fields and have many applications—both linear and nonlinear types, with some being semilinear and ...

Weak discontinuity waves in n-type semiconductors with defects of dislocation

Atti della Accademia Peloritana dei Pericolanti : Classe di Scienze Fisiche, Matematiche e Naturali, 2019
In this paper a Boillat's methodology is applied to investigate discontinuity waves of a system of quasi-linear hyperbolic partial differential equations (PDEs), describing the interactions between the electronic and dislocation fields in extrinsic ...

On the formulation and investigation of a boundary value problem for a third-order equation of a parabolic-hyperbolic type

Қарағанды университетінің хабаршысы. Математика сериясы
In the paper a novel boundary value problem for a third-order partial differential equation (PDE) of a parabolic-hyperbolic type, within a pentagonal domain consisting of both parabolic and hyperbolic regions was investigated. Such equations are pivotal
