数独秘诀

数独为一种逻辑游戏，注重逻辑与推理。本书是数独研究者、爱好者和初学者由浅入深学习数独的数学普及读物。作为介绍数独的智力游戏的图书，相比较于市面上其他以题库为主的同类书籍，本书表现出较强的学术深度和研究价值，值得一读！

本书旨在为数独爱好者和学习者提供数独游戏的规则和适用性高的解题技巧与解题思路，以帮助读者了解数独游戏，享受解题乐趣。本书介绍了数独游戏的定义和规则，逐条说明求解数独问题的运算规则及其符号，并辅以应用实例。本书还依次归纳了数条普遍适用的运算规则和一定数量的数独题目，帮助读者较快适应数独规则、轻松实践上手。

马中骐，浙江杭州（临平）人，1940年3月生于上海市。曾就读于兰州大学，是中国科学院首届研究生，获10001号博士学位证书。曾任中国科学院高能物理研究所四室研究员、博士生导师、高能物理研究所学术委员会委员和高能物理研究所学位委员会主任、高能物理学会会员。曾在规范场理论、大统一理论、磁单极理论、量子散射理论和Levinson定理、量子群理论及其在物理中的应用、群论方法在量子理论中的应用等方向开展科研工作。重要的科研成果有量子N体系统转动自由度的分离、Levinson定理的证明与推广、量子群的研究等。诺贝尔奖获得者杨振宁教授曾评价马中骐的研究成果是能留得下来的工作。 出版的图书包括《群论及其在物理中的应用》、《杨-巴克斯特方程和量子包络代数》、《物理学中的群论》、《群论习题精解》、Yang-Baxter equation and quantum enveloping algebras等。
