WebJun 20, 2024 · The first article produced from our project was published in Aligarh Mathematics Bulletin. Title: Strong commutativity preserving endomorphisms in prime rings with involution Please find the paper... WebA prime ring A is called a ∗−ring if β(A/I) = A/I for every nonzero ideal proper I of A, where β is the prime radical. Gardner in 1988 asked whether the upper radical U(∗k) of the essential closure ∗k of the class of all ∗−rings coincide with the prime radical β. Until now, this problem remains open. In this paper, we construct a graded ∗−ring that motivates a … puppies in canton texas
