Journal of Algebraic SystemsA ring $R$ is called a left $\mathcal{Z}$-symmetric ring if $ab \in \mathcal{Z}_l(R)$ implies $ba \in \mathcal{Z}_l(R)$, where $\mathcal{Z}_l(R)$ is the set of left zero-divisors. A right $\mathcal{Z}$-symmetric ring is defined similarly, and a $\mathcal{

An Equivalent Condition and Some Properties of Strong J-Symmetric Ring
Journal of Mathematics, 2021 Let JR denote the Jacobson radical of a ring R. We say that ring R is strong J-symmetric if, for any a,b,c∈R, abc∈JR implies bac∈JR. If ring R is strong J-symmetric, then it is proved that Rx/xn is strong J-symmetric for any n≥2. If R and S are rings and

On Prime and Semiprime Rings with Symmetric Generalized Biderivations
Al-Mustansiriyah Journal of Science, 2017 The propose of this paper is to present some results concerning the symmetric generalized Biderivations when their traces satisfies some certain conditions on an ideal of prime and semiprime rings.

PT symmetric dynamics in counter-rotating gyroscopic mechanical systems
AIP Advances, 2021 Parity-time (PT) symmetry was first studied in quantum mechanical systems with a non-Hermitian Hamiltonian whose observables are real-valued. Most existing designs of PT symmetric systems in electronics, optics, and acoustics rely on an exact balance of ...

Kurosh-Amitsur Right Jacobson Radical of Type 0 for Right Near-Rings
International Journal of Mathematics and Mathematical Sciences, 2008 By a near-ring we mean a right near-ring. J0r, the right Jacobson radical of type 0, was introduced for near-rings by the first and second authors. In this paper properties of the radical J0r are studied. It is shown that J0r is a Kurosh-Amitsur radical

Duo property for rings by the quasinilpotent perspective
Karpatsʹkì Matematičnì Publìkacìï, 2021 In this paper, we focus on the duo ring property via quasinilpotent elements, which gives a new kind of generalizations of commutativity. We call this kind of rings qnil-duo. Firstly, some properties of quasinilpotents in a ring are provided.

New light rings from multiple critical curves as observational signatures of black hole mimickers
Physics Letters B, 2022 We argue that the appearance of additional light rings in a shadow observation - beyond the infinite sequence of exponentially demagnified self-similar rings foreseen in the Kerr solution - would make a compelling case for the existence of black hole ...

PERFECT SYMMETRIC RINGS OF QUOTIENTS [PDF]
Journal of Algebra and Its Applications, 2009 Perfect Gabriel filters of right ideals and their corresponding right rings of quotients have the desirable feature that every module of quotients is determined solely by the right ring of quotients. On the other hand, symmetric rings of quotients have a symmetry that mimics the commutative case. In this paper, we study rings of quotients that combine

Hereditary right Jacobson radicals of type-1(e) and 2(e) for right near-rings
Analele Stiintifice ale Universitatii Ovidius Constanta: Seria Matematica, 2013 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.
