摘要 运用Fourier变换研究了一类电报方程初值问题的整体解,在一定条件下得到了这类电报方程的初值问题在一个Sobolev空间中整体解的存在性和唯一性,同时还部分地回答了初始信号对发散波长时间稳定性的影响. Using Fourier techniques,this paper deals with the global solution of an initial value problem for a class of telegraph equations. Under certain assumptions, the existence and uniqueness of the global solution for the telegraph equation are established in a suitable Sobolev space. We confirm that the long time stability of the emission wave is partly influenced by the initial input signal.
