Abstract

We show that Lemma 4.4 and Theorem 4.5 in [Zhang, X., Laan, V., Injective hulls for ordered algebras, Algebra Universalis, 76 (2016), 339–349] are incorrect. These results can be corrected by replacing unary polynomial functions by linear functions.

摘要

我们表明 [Zhang, X., Laan, V., Injective hulls for Ordered algebras, Algebra Universalis, 76 (2016), 339-349] 中的引理 4.4 和定理 4.5 是不正确的。这些结果可以通过用线性函数替换一元多项式函数来校正。
