The aim of this book is to develop the combinatorics of Young tableaux and to show them in action in the algebra of symmetric functions, representations of the symmetric and general linear groups, and the geometry of flag varieties. The first part of the book is a self-contained presentation of the basic combinatorics of Young tableaux, including the remarkable constructions of 'bumping' and 'sliding', and several interesting correspondences. In Part II these results are used to study representations with geometry on Grassmannians and flag manifolds, including their Schubert subvarieties, and the related Schubert polynomials. Much of this material has never appeared in book form.There are numerous exercises throughout, with hints or answers provided. Researchers in representation theory and algebraic geometry as well as in combinatorics will find Young Tableaux interesting and useful; students will find the intuitive presentation easy to follow.

隻仔細讀瞭第一部分關於組閤的,第二部分是錶示論,第三部分是Schubert演算,難度越來越大,會逐漸假設你的基礎知識。
評分1組閤:楊錶,Knuth等價和RSK對應;這部分比較直觀,但許多證明並不簡單,Littlewood-Richardson rule在1977年纔有第一個證明。2錶示論:S_n和GL(V)的錶示;這部分基本上self-contained,展現楊錶的威力。3幾何:Flag varieties,Schubert calculus和intersection theory;看這部分需要先瞭解代數拓撲和代數幾何。

評分後悔沒有早點瞭解Young Tableaux。有趣的是高德納(Knuth)對這理論作齣瞭重要貢獻。
