摘要
本文给出了构造弱归纳*-半环上任意两个二元仿射映射的联立不动点的一种方法,并证明了对于归纳*-半环上的二元仿射映射,这种构造实际上给出了其最小联立前不动点.
In this paper, we give a construction of simultaneous fixed points of any two binary affine maps over a weak inductive *-semiring. Moreover, we prove that for inductive * -semirings, this construction indeed gives the least simultaneous prefixed points.
