The familiar wave equation is the most fundamental hyperbolic partial differential equation. Other hyperbolic equations, both linear and nonlinear, exhibit many wave-like phenomena. The primary theme of this book is the mathematical investigation of such wave phenomena. The exposition begins with derivations of some wave equations, including waves in an elastic body, such as those observed in connection with earthquakes. Original PDE (with u ( n, m) (x, y) denoting n th partial derivative of u in x and m th in y ): Au ( 2, 0) (x, y) + 2Bu ( 1, 1) (x, y) + Cu ( 0, 2) (x, y) + Du ( 1, 0) (x, y) + Eu ( 0, 1) (x, y) = 0. Fourier-transformed one (with ˆu(kx, ky) denoting the Fourier transform of u(x, y) ): Lˆu(kx, ky) = 0, where.

Hyperbolic Partial Differential Equations - Serge Alinhac - häftad

A hyperbolic partial differential equation of order n is a partial differential equation (PDE) that, roughly speaking, has a well-posed initial value problem for the first n − 1 derivatives. More precisely, the Cauchy problem can be locally solved for arbitrary initial data along any non-characteristic hypersurface. The wave equation is an important representative of a hyperbolic equation. In this article, we have proposed a highly efficient and accurate collocation method based on Haar wavelet for the parameter identification in multidimensional hyperbolic partial differential equat HYPERBOLIC PARTIAL DIFFERENTIAL EQUATIONS This is a new type of graduate textbook, with both print and interactive electronic com-ponents (on CD). It is a comprehensive presentation of modern shock-capturing methods, including both ﬁnite volume and ﬁnite element methods, covering the theory of hyperbolic 2 Partial Differential Equations Physical problems that involve more than one variable are often expressed using equtions involving partial derivatives. And it is called Partial Differential Equation (PDE’s). There are three types of partial differential equations. 3 Types of Partial Differential Equations (PDEs) 1) Elliptic: The solution of the fractional hyperbolic partial differential equation is obtained by means of the variational iteration method.
