Leclerc猜想期望对偶标准基满足一定的(双重)三角性质。我们对量子簇代数的公共三角基提出了一个类似的猜想。我们证明了类似猜想的一个较弱形式是正确的。我们的结果适用于量子幂幺子群的对偶标准基。它也适用于量子仿射代数的单模的q-特征标的t-模拟。
Dual canonical bases are expected to satisfy a certain (double) triangularity property by Leclerc's conjecture. We propose an analogous conjecture for common triangular bases of quantum cluster algebras. We show that a weaker form of the analogous conjecture is true. Our result applies to the dual canonical bases of quantum unipotent subgroups. It also applies to the t-analogs of q-characters of simple modules of quantum affine algebras.
