论文摘要
如果对于每个非零元素$ x $，则有两个非零中央元素$ y，z $，其中$ xy = z $，据说一个半序列至关重要。我们提供了一些非交互性中心基本半段的示例，并描述了添加性取消中心基本半段的一些特性。
A semiring is said to be centrally essential if for every non-zero element $x$, there exist two non-zero central elements $y, z$ with $xy = z$. We give some examples of non-commutative centrally essential semirings and describe some properties of additively cancellative centrally essential semirings.
