A brief survey of Kazhdan-Lusztig theory and related topics. (English) Zbl 0836.20060
Haboush, William J. (ed.) et al., Algebraic groups and their generalizations: classical methods. Summer Research Institute on algebraic groups and their generalizations, July 6-26, 1991, Pennsylvania State University, University Park, PA, USA. Providence, RI: American Mathematical Society. Proc. Symp. Pure Math. 56, Pt. 1, 105-124 (1994).
The survey deals mainly with multiplicities of Verma modules, Kazhdan- Lusztig polynomials, the conjectures by Jantzen and Kazhdan-Lusztig about them, and the proofs of the conjectures. The author outlines in some detail his results on parabolic analogues and explicit calculation of the Kazhdan-Lusztig polynomials [see for instance J. Algebra 111, 483-506 (1987; Zbl 0656.22007) and Geom. Dedicata 36, 95-119 (1990; Zbl 0716.17015)]. A list of 160 references to relevant articles concludes the survey.
