The aim of the paper is to characterize the equation 1 + Δ ( R ) = U ( R ) , where J ( R ) ⊆ Δ ( R ) = { x ∈ R : x + u ∈ U ( R ) for all u ∈ U ( R ) } that is the largest Jacobson radical subring of R and U ( R ) is the set of invertible elements of a ring R . We show that this equation is closely related to U J -rings and rings whose elements can be written as the sum of an idempotent and an element from Δ ( R ) . After presenting several characterizations and properties of this equation, we consider the rings satisfying the equation 1 + Δ ( R ) = U ( R ) within many well-studied classes of rings. Finally, we close the paper with group rings.

UJ环的概括
本文的目的是描述方程1 + Δ ( R ) = ü ( R ) , 在哪里Ĵ ( R ) ⊆ Δ ( R ) = { X ∈ R : X + 你 ∈ ü ( R ) 对所有人 你 ∈ ü ( R ) } 这是最大的 Jacobson 激进子环R 和ü ( R ) 是环的可逆元素的集合R . 我们证明这个方程与ü Ĵ -环和环,其元素可以写为幂等和元素之和Δ ( R ) . 在介绍了这个方程的几个特征和性质之后,我们考虑满足方程的环1 + Δ ( R ) = ü ( R ) 在许多经过充分研究的环类中。最后,我们用群环关闭论文。
