摘要: 研究环与其圈半群的关系. 利用圈乘刻画了伴随Clif ford环和有小圈半群的环, 构造了一个交换的伴随Clifford环, 其Jacobson根不是直和项, 从而证实了Heatherly和Tucci的一个猜测.

关键词: 圈半群, 伴随Clifford环, 小幺半群

Abstract: This paper deals with the relationship between a ring and its circle semigroup. Adjoint clifford rings and the rings with small circle semigroups are characterized in terms of circle multiplication, and a commutative adjoint Clifford ring is constructed in which Jacobson radical is not a summand so as to confirm a conjecture of Heatherly and Tucci.

Key words: circle semigroup, adjoint Clifford ring, small monoid
