内容大纲
扩展图是理论计算机科学、几何群论、概率论和数论中的重要工具。而用于严格建立图的扩展性质的技术来自表示论、代数几何和算术组合学等数学的不同领域。围绕后一主题，本书着重讨论了Lie型有限群上的Cayley图的重要情形，发展了诸如Kazhdan性质（T）、拟随机性、乘积估计、从子簇中逃逸以及Balog-Szemerédi-Gowers引理等工具，还给出了Bourgain、Gamburd和Sarnak的仿射筛法的应用。本书内容在很大程度上是自封的，增加了关于扩展子、谱理论、Lie理论和Lang-Weil界的一般理论的内容，并包含大量习题和其他可选材料。
本书适合对图论、几何群论和算术组合学感兴趣的研究生和数学研究人员阅读参考。
