Line bundles on flag manifolds. (English) Zbl 0531.20022
Astérisque 87-88, 21-42 (1981).
In the paper under review the author gives a survey of some recent results on cohomology of line bundles on flag manifolds. It covers mostly the author’s own contributions to the theory but it also includes a brief account of the history of the subject. In the last section he mentions some of the other works that have been done in the area. A couple of open problems are also briefly discussed.
The following sections are in the paper. 1. The problem. 2. A little history. 3. \(H^ 1\) [cf. H. H. Andersen, Invent. Math. 51, 287-296 (1979; Zbl 0417.20038)]. 4. The linkage principle [cf. H. H. Andersen, J. Reine Angew. Math. 315, 53-59 (1980; Zbl 0439.20026)]. 5. Further vanishing results. 6. An isomorphism theorem. 7. Related results and some open problems. The list of references includes 45 items.
