內容簡介:　　環(huán)簇構成了現(xiàn)代代數(shù)幾何中優(yōu)美且易于理解的一部分。
　　《環(huán)簇（影印版）》涵蓋了環(huán)幾何中的標準主題，一個顯著特色是前九章的每一章都包含了導引，用于交待代數(shù)幾何中必要的背景知識。
　　《環(huán)簇（影印版）》涵蓋的其他主題包括商構造、消逝定理、等變上同調、GIT商、次要扇及針對環(huán)簇的極小模型綱領。環(huán)簇有豐富的例子，這反映在書中的134幅插圖中。
　　《環(huán)簇（影印版）》同樣探究了交換代數(shù)與多面體幾何的聯(lián)系，討論了多胞體及其無界的孿生體一一多面體。書后有兩個附錄，分別介紹了環(huán)簇的歷史和用以考察環(huán)幾何中非平凡例子的計算工具。
　　《環(huán)簇（影印版）》讀者應熟悉研究生基礎課程所涉及的代數(shù)和拓撲知識，以及程度略低一點的復分析知識。此外，作者假定讀者具備一定程度的高年級本科生水平的代數(shù)幾何知識。
　　《環(huán)簇（影印版）》對于對代數(shù)幾何、多面體幾何和環(huán)簇感興趣的研究生和研究人員是一本好參考書。
