Unitary Strongly Prime Rings and Related Radicals
A unitary strongly prime ring is defined as a prime ring whose central closure is simple with identity element. The class of unitary strongly prime rings is a special class of rings and the corresponding radical is called the unitary strongly prime radical. In this paper we prove some results on unitary strongly prime rings. The results are applied to study the unitary strongly prime radical of...
متن کاملHereditary properties of permutations are strongly testable
We show that for every hereditary permutation property P and every ε0 > 0, there exists an integer M such that if a permutation π is ε0far from P in the Kendall’s tau distance, then a random subpermutation of π of order M has the property P with probability at most ε0. This settles an open problem whether hereditary permutation properties are strongly testable, i.e., testable with respect to th...
متن کاملWhen are radicals of Lie groups lattice-hereditary?
This note aims to clarify what conditions on a connected Lie group G imply that its maximal connected normal solvable subgroup R intersects each lattice of G as a lattice in R.
متن کاملHereditary right Jacobson radicals of type-1(e) and 2(e) for right near-rings
Near-rings considered are right near-rings. In this paper two more radicals, the right Jacobson radicals of type-1(e) and 2(e), are introduced for near-rings. It is shown that they are Kurosh-Amitsur radicals (KAradicals) in the class of all near-rings and are ideal-hereditary radicals in the class of all zero-symmetric near-rings. Different kinds of examples are also presented.
