Reversibility of tubal ring sterilization
Contraception, 1977Abstract The reversibility of the tubal ring sterilization technique was studied in 22 rabbits. Using microsurgery for end-to-end reanastomosis, a patency rate of 96% and a pregnancy rate of 86% was obtained. It is suggested that human tubal ring sterilization has a high probability of being reversible, although several factors of reversibility ...

Bulletin of the London Mathematical Society, 1999
A ring \(R\) is called reversible if \(ab=0\) implies \(ba=0\); it is insertable if \(ab=0\) implies \(aRb=0\). Clearly any reversible ring is insertable, but not conversely. The author proves that a ring is (i) an integral domain if and only if it is prime and reversible (insertable), (ii) reduced if and only if it is semiprime and reversible ...

Generalizations of reversible and Armendariz rings
International Journal of Algebra and Computation, 2016This paper concerns several ring theoretic properties related to matrices and polynomials. The basic properties of [Formula: see text]-reversible and power-Armendariz are studied. We provide a method by which one can always construct a power-Armendariz ring but neither symmetric nor Armendariz from given any symmetric ring. We investigate next various

RING ENDOMORPHISMS WITH THE REVERSIBLE CONDITION [PDF]
Communications of the Korean Mathematical Society, 2010 P. M. Cohn called a ring R reversible if whenever ab = 0, then ba = 0 for a,b 2 R. Commutative rings and reduced rings are reversible. In this paper, we extend the reversible condition of a ring as follows: Let R be a ring and fi an endomorphism of R, we say that R is right (resp., left) fi-shifting if whenever afi(b) = 0 (resp., fi(a)b = 0) for a,b 2 ...

e-reversibility of rings via quasinilpotents
Georgian Mathematical Journal, 2023Abstract The reversible property of rings was introduced by Cohn and has important generalizations in noncommutative ring theory. In this paper, reversibility of rings is investigated in relation with quasinilpotents and idempotents, and our argument is spread out based on this. We call a ring R Qnil e-reversible if for

On duo, reversible and symmetric group rings
Sao Paulo Journal of Mathematical SciencesLet $RG$ denote the group ring of the torsion group $G$ over a commutative ring $R$ with identity. In this paper we present proofs of some statements that appear without to be proved in the literature. We establish the valid implications between the ring-theoretic conditions duo, reversible, SI property and symmetric in the setting of group rings.

On a property of polynomial rings over reversible rings
Communications in Algebra, 2018In this article, we first observe a sort of property of ideals generated by zero-dividing polynomials over reversible rings, in relation with products of ideals at zero.
