A nil approach to symmetricity of rings
Üngör, B.; Köse, H.; Kurtulmaz, Yosum; Harmancı, A. (Allahabad Mathematical Society, 2018)We introduce a weakly symmetric ring which is a generalization of a symmetric ring and a strengthening of both a GWS ring and a weakly reversible ring, and investigate properties of the class of this kind of rings. A ring ... 
Reflexivity of rings via nilpotent elements
Harmancı, A.; Köse, H.; Kurtulmaz, Yosum; Üngör, B. (Union Matematica Argentina, 2020)An ideal I of a ring R is called left Nreflexive if for any a ∈ nil(R) and b ∈ R, aRb ⊆ I implies bRa ⊆ I, where nil(R) is the set of all nilpotent elements of R. The ring R is called left Nreflexive if the zero ideal ... 
Rings having normality in terms of the Jacobson radical
Köse, H.; Kurtulmaz, Yosum; Harmancı, A. (Springer, 2020)A ring R is defined to be Jnormal if for any a,r∈Ra,r∈R and idempotent e∈Re∈R, ae=0ae=0 implies Rera⊆J(R)Rera⊆J(R), where J(R) is the Jacobson radical of R. The class of Jnormal rings lies between the classes of weakly ... 
Rings in which elements are a sum of a central and a unit element
Kurtulmaz, Yosum; Halıcıoğlu, S.; Harmancı, A.; Chen, H. (The Belgian Mathematical Society, 2019)In this paper we introduce a new class of rings whose elements are a sum of a central and a unit element, namely a ring RR is called CUCU if each element a∈Ra∈R has a decomposition a=c+ua=c+u where cc is central and uu is ... 
Semicommutativity of amalgamated rings
Köse, H.; Kurtulmaz, Yosum; Üngör, B.; Harmancı, A. (Journal of Mathematical Research with Applications, 2018)In this paper, we study some cases when an amalgamated construction A ◃▹f I of a ring A along an ideal I of a ring B with respect to a ring homomorphism f from A to B, is prime, semiprime, semicommutative, nilsemicommutative ...
