2. 短课程介绍

    课程名: Duality for coherent sheaves(凝聚层的对偶理论)

    摘要: Grothendieck duality theory is a powerful tool for the study of the cohomological groups of coherent sheaves over algebraic varieties. This short course is an introduction to this theory for families of projective varieties. Main references are Hartshorne’s book,  III.6-7 and Kleiman’s paper (Compositio Math. 1980).

 

    中文简介:Grothendieck 对偶理论是研究代数簇上凝聚层的上同调群的强大工具,该短课程介绍该理论的一个主要情形:关于一族射影簇的上同调的对偶理论。

    主要参考文献:Hartshorne 的书III.6-7节,Kleiman 的论文(Compositio Math 1980.
