Sur la nature de l’equation generale d’une onde du 2nd ordre a symetrie centrale

Pomégnon Komivi Siliadin, Kokou Tcharie

Abstract


A l’aide d’un changement de variable avec l’utilisation de l’opérateur de Bessel, on établit que l’équation d’onde générale du 2nde ordre à symétrie centrale est une équation de type hyperbolique.

Mots clés: Equation d’onde, symétrie centrale, opérateur de Bessel, forme canonique

English Title: On the nature of the general equation of second order wave with central symetry

English Abstract

By a variable changing and using Bessel operator, one etablises that the general wave equation of 2nd order with central symmetry is an hyperbolic type equation.

Keywords: Wave equation, central symmetry, Bessel operator, canonic form
