摘要：
In this paper, we give a sufficient and necessary condition for a regular element of a quantum cluster algebra O q ( X ) to be universally polynomial. This resolves several conjectures by the first author on the polynomiality of the cluster realization of quantum group generators in different families of positive representations.
