关于卷积的有限积与双曲型和椭圆型方程的分类

On Finite Product of Convolutions and Classifications of Hyperbolic and Elliptic Equations

A. Kilicman, H. Eltayeb

摘要:

本文考虑了二阶变系数线性偏微分方程,利用二重卷积积得到了新的多项式系数方程,并对新方程进行了分类.证明了双曲型和椭圆型新方程的分类与原方程的分类是相似的,即在有限次双卷积积后分类不变。

英文摘要:

In this paper we consider the linear second order partial differential equation with non-constant coefficients; then by using the double convolution product we produce new equations with polynomials coefficients and we classify the new equations. It is shown that the classifications of hyperbolic and elliptic new equations are similar to the original equations that is the classification is invariant after finite double convolutions product.
