Bitableaux and Zero Sets of Dual Canonical Basis Elements
We state new results concerning the zero sets of polynomials belonging to the dual canonical basis of C[x1,1, . . . , xn,n]. As an application, we show that this basis is related by a unitriangular transition matrix to the simpler bitableau basis popularized by Désarménien-Kung-Rota. It follows that spaces spanned by certain subsets of the dual canonical basis can be characterized in terms of p...
متن کاملQuantum Unipotent Subgroup and Dual Canonical Basis
In a series of works [18, 21, 19, 20, 23, 22], Geiß-Leclerc-Schröer defined the cluster algebra structure on the coordinate ring C[N(w)] of the unipotent subgroup, associated with a Weyl group element w. And they proved cluster monomials are contained in Lusztig’s dual semicanonical basis S∗. We give a set up for the quantization of their results and propose a conjecture which relates the quant...
متن کاملImaginary vectors in the dual canonical basis of Uq(n)
Let n be the maximal nilpotent subalgebra of a simple complex Lie algebra g. We introduce the notion of imaginary vector in the dual canonical basis of Uq(n), and we give examples of such vectors for types An(n > 5), Bn(n > 3), Cn(n > 3), Dn(n > 4), and all exceptional types. This disproves a conjecture of Berenstein and Zelevinsky about q-commuting products of vectors of the dual canonical bas...
متن کاملZero sets in pointfree topology and strongly $z$-ideals
In this paper a particular case of z-ideals, called strongly z-ideal, is defined by introducing zero sets in pointfree topology. We study strongly z-ideals, their relation with z-ideals and the role of spatiality in this relation. For strongly z-ideals, we analyze prime ideals using the concept of zero sets. Moreover, it is proven that the intersection of all zero sets of a prime ideal of C(L),...
متن کاملJ an 2 00 2 Dual Standard Monomial Theoretic Basis and Canonical Basis for Type A
Let U − q (g) be the negative part of the quantized universal enveloping algebra constructed from a Cartan matrix associated to a complex semisimple Lie algebra g. Let λ be a dominant integral weight and V (λ) the irreducible U − q (g)-module with highest weight λ. There is on the one hand the canonical basis for U − q (g) [4, 12, 13] and on the other the standard monomial theoretic basis for t...
