Singular Loci of Schubert Varieties

"Singular Loci of Schubert Varieties is a work at the crossroads of representation theory, algebraic geometry, and combinatorics. In this work, Billey and Lakshmibai have recreated and restructured the various theories and approaches of those articles and present a clearer understanding of this important subdiscipline of Schubert varieties - namely singular loci."--BOOK JACKET.
