Shen, Xiaoqin; Tian, Jing; Feng, Pihu On commutative weak inductive *-semirings. (Chinese. English summary) Zbl 1274.16068 Pure Appl. Math. 28, No. 4, 540-545 (2012). Summary: The semiring \(S^{2\times 2}\) of \(2\times 2\) matrices over a commutative weak inductive \(^*\)-semiring \(S\) is studied. It is shown that if \(S^{2\times 2}\) is a \(\lambda\)-semiring then it is a weak inductive \(^*\)-semiring again. Then the least simultaneous fixed points of two binary affine maps over \(S\) are given.
