Abstract
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-Gelâfand-Gelâfand on ordinary cohomology and of Kostant-Kumar on $K$-theory. Bott-Samelson resolutions are used to replace the classical basis of Schubert cells.
