给出了A型和A型任意系数自由簇代数的显式原子基。这需要证明这些簇代数的正半环的极小元在簇代数的整数上形成一个线性基。
We give explicit atomic bases of arbitrary coefficient‐free cluster algebras of types A and Ã. This entails showing that the minimal elements of the positive semiring of these cluster algebras form a linear basis over the integers for the cluster algebra.
