研究了紧连通李群的旗簇的复余边环的结构。推广了Bernstein-Gel‘fand-Gel’fand-Gel‘fand关于普通上同调的工作和Kostant-Kumar关于K-理论的工作,得到了确定基元乘积的一个显式过程。用Bott-Samelson分解代替经典的Schubert胞基
We study the structure of the complex cobordism ring of the flag variety of a compact connected Lie group. An explicit procedure for determining products of basis elements is obtained, generalizing the work of Bernstein-Gel'fand-Gel'fand on ordinary cohomology and of Kostant-Kumar on K-theory. Bott-Samelson resolutions are used to replace the classical basis of Schubert cells
