Strong prüfer rings and the ring of finite fractions
Journal of Pure and Applied Algebra, 1993 Let \(R\) be a commutative ring with identity, \(T(R)\) its total quotient ring, and \(Q(R)\) its complete ring of quotients. Denote by \(Q_ 0(R)\) the ring of finite fractions of \(R\), which is a subring of \(Q(R)\) containing \(T(R)\). The author defines a \(Q_ 0\)-Prüfer ring as a ring \(R\) for which every ring between \(R\) and \(Q_ 0(R)\) is ...

A Theorem on Finite Generation of a Ring [PDF]
Nagoya Mathematical Journal, 1966 The fourteenth problem of Hilbert asked finite generation of a certain class of rings and had a counter-example (cf. [4]). On the other hand, many mathematicians gave various sufficient conditions for finite generation of such rings (see, for instance, [9], [5] and [8]). The purpose of the present paper is to give a new sufficient condition.

Advanced Engineering Materials, EarlyView.Different Al/Al bimetals with a single engineered interface reveal how mechanical mismatch governs fatigue crack growth under cyclic loading. Additionally, loading–unloading–reloading tests link the microyielding behavior to the fatigue crack growth resistance, while crack‐path analysis reveals toughening mechanisms at the interface, highlighting ...

Rings with a finite set of nonnilpotents
International Journal of Mathematics and Mathematical Sciences, 1979 Let R be a ring and let N denote the set of nilpotent elements of R. Let n be a nonnegative integer. The ring R is called a θn-ring if the number of elements in R which are not in N is at most n. The following theorem is proved: If R is a θn-ring, then R

Advanced Engineering Materials, EarlyView.Schematic representation of modes of microcrack nucleation, growth and temporary arrestment at different boundaries, with the criteria for crack propagation in three scenarios: (1) large notch, (2) defect/small sharp notch, and (3) long crack. This work revisits and integrates results on the fatigue behavior of advanced bainitic steels (in particular ...

Locally Finite Ring Varieties [PDF]
Proceedings of the American Mathematical Society, 1975 Necessary and sufficient conditions are given for a variety of associative rings to be locally finite. These conditions are utilized to show that a variety is generated by a finite ring if, and only if, it contains only finitely many subvarieties.

Advanced Engineering Materials, EarlyView.Solvate ionic liquids lubrication reduced the coefficient of friction by ∼60% compared to dry sliding, reaching steady‐state values as low as 0.04–0.05. Corrosion weight‐loss measurements in 1 M HCl further demonstrated significant inhibition behavior, with only 100 ppm of [Li(G3)][TFSI] (∼68.5 μL/L) reducing corrosion‐product weight loss by 63 ...

On the structure of one-generated Leibniz rings
Researches in MathematicsThe paper is devoted to the study of one-generated Leibniz rings. We begin with a short discussion of the relation between Lie rings, Lie algebras, Leibniz algebras, and Leibniz rings, and recall the basic notions needed in the sequel.
