Nonlinear Waves in Inhomogeneous and Hereditary Media

• Broschiertes Buch

Produktbeschreibung

This monograph presents the study of one-dimensional waves

in inhomogeneous and hereditary media (i.e., media with

memory). A new mathematically rigorous factorization method

is applied which yields either an exact or an asymptotic

decomposition of the nonlinear wave equations under

consideration into first order multipliers.

A central result presented in the book is a factorization

theorem for the simple wave equation with constant

coefficients. It permits to view Riemann invariants and

simple waves from a different angle and is used to go over

to wave equations with variable coefficients and memory.

Dieser Band liefert eine Studie über eindimensionale Wellen in inhomogenen und hereditaren Medien (d.h. Medien mit "Gedächtnis"). Die Autoren wenden eine neue, mathematisch exakte Faktorisierungsmethode an, die entweder zur exakten oder zur asymptotischen Zerlegung nichtlinearer Wellengleichungen in Multiplikatoren erster Ordnung führt.
