Weakly Hyperbolic Equations — A Modern Field in the Theory of Hyperbolic Equations [PDF]

, 1999
In the last two decades the theory of weakly hyperbolic equations was developed in gin astonishing way. The goal of the paper is to give new directions which were discussed in recent years. In section 2 the Cauchy problem is discussed for a model quasilinear weakly hyperbolic equation with time and spatial degeneracy.

Quasi-Hyperbolicity and Delay Semigroups

Abstract and Applied Analysis, 2016
We study quasi-hyperbolicity of the delay semigroup associated with the equation u′(t)=Bu(t)+Φut, where ut is the history function and (B,D(B)) is the generator of a quasi-hyperbolic semigroup.

Comparison of hyperbolic and parabolic equations modelling buoyancy driven flow in a square cavity

Partial Differential Equations in Applied Mathematics
The effects of a hyperbolic and parabolic heat transfer equation on buoyancy-driven flow in a square cavity are studied. Boundary conditions where the bottom wall is hot and the side and top walls are cold are investigated.

Three-dimensional integro-multipoint boundary value problem for loaded Volterra-hyperbolic integro-differential equations of Bianchi type

Vestnik Samarskogo Gosudarstvennogo Tehničeskogo Universiteta. Seriâ: Fiziko-Matematičeskie Nauki, 2012
In this paper the combined three-dimensional non-local boundary value problem with integro-multipoint conditions for loaded volterra-hyperbolic integro-differential equation of Bianchi type is explored.

Manifold spines and hyperbolicity equations

, 2001
The authors present a combinatorial representaion of gluing 3-manifolds and their special spines. This is done using graphs encoded by \(\gamma\)-tuples of non-negative integers. More precisely, they use the result of Casler which states that two 3-manifolds with homeomorphic special spines are homeomorphic.

Hyperbolic approximation of the fourier transformed vlasov equation

ESAIM: Proceedings and Surveys, 2014
We construct an hyperbolic approximation of the Fourier transformed Vlasov equation in which the dependency on the spectral-velocity variable is removed. The model is constructed from the Vlasov equation after a Fourier transformation
