內容簡介

　　This book is composed of two parts: Part I （Chaps. I through 3） is an introduction to tensors and their physical applications， and Part II （Chaps. 4 through 6） introduces group theory and intertwines it with the earlier material. Both parts are written at the advanced-undergraduate/beginning graduate level， although in the course of' Part II the sophistication level rises somewhat. Though the two parts differ somewhat in flavor，l have aimed in both to fill a （perceived） gap in the literaiure by connecting
　　the component formalisms prevalent in physics calculations to the abstract but more conceptual formulations found in the math literature. My firm beliefis that we need to see tensors and groups in coordinates to get a sense of how they work， but also need an abstract formulation to understand their essential nature and organize our thinking about them.

缺頁..............

以前從來不評論的，不知道浪費多少積分，自從知道評論可以得到積分以後，每次來這裏復製粘貼

評分☆☆☆☆☆

一般般吧，比較經典的群論書。

評分☆☆☆☆☆

書質量沒有問題。不過這次速度實在太慢，而且包裝那麼差，箱子的四個角全都爛瞭。不像京東的作風。綜閤三分

評分☆☆☆☆☆

不錯，活動時買的，很給力。

經典書籍，買來收藏，以後應該會用到。

看著不錯
