Abstract This chapter is an introduction to hyperbolic equations. The topic is of central importance in general relativity since the Einstein evolution equations are themselves essentially hyperbolic as are the equations of motion of many of the matter fields frequently used. The qualification ‘essentially’ is explained in Chapter 9.

Abstract Hyperbolic equations are the easiest scalar second-order equations to classify from the point of view of the Cauchy problem. They occur commonly in practical applications, as is evident from studying the models of Chapter 2.

On the Domain of Hyperbolicity of the Cumulant Equations
Journal of Statistical Physics, 2005The first part of this paper gives an overview on modeling flow of a non-reacting mixture of gases by kinetic theory and how to derive approximate, mesoscopic model equations, the moment equations. The second part gives a short overview of the cumulant method, an alternative method of approximation that results in particularly simple equations.

On Hyperbolic Partial Differential Equations
American Journal of Mathematics, 1952where p = zx, q = zy, it is assumed that f is continuous in (x, y, z, p, q) and satisfies a uniform Lipschitz conditioni with respect to (z, p, q). It will be shown (Section 2) that the assumption of a Lipschitz. condition with respect to z can be omitted in these existence theorems, though not in the uniqueness theorems.

Semilinear equations in the “hyperbolic” case
Nonlinear Analysis: Theory, Methods & Applications, 1995The author obtains a `generalized variation of constants formula' for the solutions in generalized sense to the inhomogeneous initial value problem (A) \(u'(t)= A(t) u(t)+ f(t)\) for \(t\in [0, T]\), \(u(0)= x\), where \(\{A(t)\}\) is a family of closed linear operators in \(X\) satisfying all conditions corresponding to the `hyperbolic' case except ...

Composite Methods for Hyperbolic Equations
SIAM Journal on Numerical Analysis, 1977A composite scheme is presented which combines the properties of the Lax–Wendroff and leapfrog algorithms. The stability properties in one dimension are analyzed for both the pure initial value and for the initial boundary value problem. In two space dimensions one must be careful which generalization of Lax–Wendroff and which generalization of ...
