Titles and abstracts. ... Bernard Leclerc; On the dual canonical basis (old and new) . Around 1991, Lusztig, motivated by earlier works of Gelfand and Zelevinsky, introduced a "canonical basis" of the coordinate ring C[N] of the maximal unipotent subgroup N of a simple algebraic group G. This basis was in fact the specialization as q tends to 1 of the dual canonical basis of the quantum enveloping algebra U_q(n) (where n = Lie(N)). ...
