چکیده

We show that dual canonical basis elements of the quantum polynomial ring in n variables can be expressed as specializations of dual canonical basis elements of 0-weight spaces of other quantum polynomial rings. Our results rely upon the natural appearance in the quantum polynomial ring of Kazhdan-Lusztig polynomials, Rpolynomials, and certain single and double parabolic generalizations of these. Résumé. Nous démontrons que des éléments de la base canonique duale de l’anneau quantique des polynômes en n variables peuvent s’exprimer en termes des spécialisations d’éléments de la base canonique duale des espaces de poids 0 d’autres anneaux quantiques. Nos résultats dependent fortement de l’apparition naturelle des polynômes de Kazhdan-Lusztig, des R-polynômes, et de certaines généralisations simplement et doublement parapoliques de ces polynômes dans l’anneau quantique.

On the Dual Canonical and Kazhdan-lusztig Bases and 3412, 4231-avoiding Permutations

Using Du’s characterization of the dual canonical basis of the coordinate ring O(GL(n,C)), we express all elements of this basis in terms of immanants. We then give a new factorization of permutations w avoiding the patterns 3412 and 4231, which in turn yields a factorization of the corresponding Kazhdan-Lusztig basis elements C w(q) of the Hecke algebra Hn(q). Using the immanant and factorizat...

The Cluster and Dual Canonical Bases of Z

The polynomial ring Z[x11, . . . , x33] has a basis called the dual canonical basis whose quantization facilitates the study of representations of the quantum group Uq(sl3(C)) [8] [5]. On the other hand, Z[x11, . . . , x33] inherits a basis from the cluster monomial basis of a geometric model of the type D4 cluster algebra [3] [4]. We prove that these two bases are equal. This extends work of S...

Determination of a Matrix Function in the Form of f(A)=g(q(A)) Where g(x) Is a Transcendental Function and q(x) Is a Polynomial Function of Large Degree Using the Minimal Polynomial

Matrix functions are used in many areas of linear algebra and arise in numerical applications in science and engineering. In this paper, we introduce an effective approach for determining matrix function f(A)=g(q(A)) of a square matrix A, where q is a polynomial function from a degree of m and also function g can be a transcendental function. Computing a matrix function f(A) will be time- consu...
