PDE入门必看,但也仅限于入门
这篇书评可能有关键情节透露
从大二上学微分方程1到大四毕业,这本书的大部分陆陆续续读完。除了第3、10章基本都读过并且验证过几乎所有细节,完成过绝大部分习题。结合现在的经验来看,这本书是PDE入门的最佳书籍。但也仅限于入门,因为内容实在是太浅太浅了。 个人认为第2、4章可以大二期间读完,第三章... (展开)> 更多书评 1篇

这影印版。。。感觉和原版没啥区别,纸质超好。印得根本分不出来是影印的。

看了前九章,我可能不适合pde。

跟着课上学了两遍,当然没全讲。个人感觉是不适合功底差的自学,需要老师带或者讨论,大佬请无视。优点显而易见,缺点有些地方巨跳+仍有很多重要的技术没涉及,毕竟已经够厚了。
