| 摘 要： | 小波配点法求解偏微分方程的研究已经有了一系列的结果,但是其解的存在惟一性仍未讨论。以抛物型方程为模型,构造了小波配点法,给出了隐格式和显格式解的存在惟一性。通过数值算例验证了该理论的可行性。

| Abstract: | The study of the numerical solutions of PDEs with wavelet collocation has yielded a number of substantial results. However, the existence and uniqueness of the solution has not been discussed. The existence and uniqueness of the solution of parabolic equations with wavelet collocation are established and discussed, where its explicit scheme and implicit scheme are given. Also, wavelet collocation is applied to parabolic equations to examine its appropriateness.
