出版时间:2011年版
内容简介
  《曲线模》是Springer数学研究生教材系列之一,全面而深入地讲述了曲线模这个科目,即代数曲线及其在族中是如何变化的。《曲线模》对曲线模的讲述,符合学习理解的规律,也是对该领域的广泛而简洁的概述,使得具有现代代数几何背景的读者很容易学习理解。书中包括了许多技巧,如Hilbert空间,变形原理,稳定约化,相交理论,几何不变理论等,曲线模型的讲述涉及从例子到应用。文中继而讨论了曲线模空间的构成,通过有限线性系列说明了Brill-Noether和Gieseker-Petri定理证明的典型应用,也讲述了一些有关不可约性,完全子变量,丰富除子和Kodaira维数的重要几何结果。书中也包括了该领域相当重要的重要定理几何开放性问题,但只是做了简明引入,并没有展开讨论。书中众多的练习和图例,使得内容更加丰富,易于理解。
