Fock和Goncharov在Fock和Goncharov(Ann. Sci.等。诺姆Supér.42(6),865-930)。同时,在Bossinger等人(Compos. 156(10),2149-2206)。在本文中,我们表明,这两个结构是兼容的-我们扩展的Fock-Goncharov量子化的品种的家庭Bossinger等。156(10),2149-2206)。作为推论,我们得到这些家庭和他们的每一个纤维具有泊松结构。我们将这种构造与Berenstein-Zelevinsky簇的量子化联系起来(Berenstein and Zelevinsky,Adv. Math.195(2),405-455,)。最后,受Lee等人(Proc. Natl. Acad. Sci.111(27),9712-9716,),我们计算了量子theta基的量子正性的反例。
Fock and Goncharov described a quantization of cluster-varieties (also known ascluster Poisson varieties) in Fock and Goncharov (Ann. Sci. Éc. Norm. Supér.42(6), 865–930 ). Meanwhile, families of deformations of cluster-varieties were introduced in Bossinger et al. (Compos. Math.156(10), 2149–2206, ). In this paper we show that the two constructions are compatible– we extend the Fock-Goncharov quantization of-varieties to the families of Bossinger et al. (Compos. Math.156(10), 2149–2206, ). As a corollary, we obtain that these families and each of their fibers have Poisson structures. We relate this construction to the Berenstein-Zelevinsky quantization of-varieties (Berenstein and Zelevinsky, Adv. Math.195(2), 405–455, ). Finally, inspired by the counter-example to quantum positivity of the quantum greedy basis in Lee, et al. (Proc. Natl. Acad. Sci.111(27), 9712–9716, ), we compute a counter-example to quantum positivity of the quantum theta basis.
