针对积分方程的求解问题,本文提出了利用卷积运算及其卷积定理来讨论两类卷积类积分方程组的解.首先,在线性正则正弦变换与线性正则余弦变换的基础上,定义了线性正则正余弦卷积运算及其加权卷积运算;其次,推导了相应的卷积定理,研究了该卷积与傅里叶正余弦变换卷积运算的关系;最后,讨论了两类卷积类积分方程组的解,给出了该方程解的一般形式.
The Weighted Convolution for the Linear Canonical Sine-Cosine Transform and Its Applications
In this paper,the convolution operation and convolution theorem are used to discuss the solutions of two kinds of convolution integral equations.Firstly,based on the linear canonical sine transform and linear canonical cosine transform,the linear canonical sine-cosine convolution operation and weighted convolution operation are defined.Secondly,the corresponding convolution theorem is derived,and the relationship between the convolution defined in this paper and the Fourier sine and Fourier cosine convolution is studied.Finally,the solutions of two kinds of convolution integral equations are discussed,and the explicit solution are also given.
