THE SPACE OF FINITELY GENERATED RINGS [PDF]
International Journal of Algebra and Computation, 2009 The space of marked commutative rings on n given generators is a compact metrizable space. We compute the Cantor–Bendixson rank of any member of this space. For instance, the Cantor–Bendixson rank of the free commutative ring on n generators is ωn, where ω is the smallest infinite ordinal.

Thermal Effects on Diesel Engine Piston and Piston Compression Rings [PDF]
Engineering and Technology Journal, 2009 This paper introduces an analytical study on the thermal effects on the diesel engine piston and its compresion rings during the contact between the piston and its compression rings .A three dimensional finite element model is built for the piston and ...

The Equivalence Problem for Finite Rings
Journal of Symbolic Computation, 1993 The equivalence problem (e.p.) for a ring is the problem of determining when two ring terms define the same function on the ring. Whereas \textit{H. B. Hunt} and \textit{R. E. Stearns} have earlier proved [ibid. 10, 411-436 (1990; Zbl 0724.68050)] for a finite ring \(R\) that: \(R\) is nilpotent implies the e.p.

International Journal of Mathematics and Mathematical Sciences, 1994 According to general terminology, a ring R is completely primary if its set of zero divisors J forms an ideal. Let R be a finite completely primary ring. It is easy to establish that J is the unique maximal ideal of R and R has a coefficient subring S (i.

On torsion-free periodic rings
International Journal of Mathematics and Mathematical Sciences, 2005 We characterize several large classes of periodic rings: periodic rings with identity, finite-rank torsion-free periodic rings, and rank-two torsion-free periodic rings.

Constacyclic codes over finite local Frobenius non-chain rings of length 5 and nilpotency index 4
Analele Stiintifice ale Universitatii Ovidius Constanta: Seria Matematica, 2020 The family of finite local Frobenius non-chain rings of length 5 and nilpotency index 4 is determined, as a by-product all finite local Frobenius non-chain rings with p5 elements (p a prime) and nilpotency index 4 are given.

CoRR, 2021 A (control) network over a finite ring is proposed. Using semi-tensor product (STP) of matrices, a set of algebraic equations are provided to verify whether a finite set with two binary operators is a ring. It is then shown that the STP-based technique developed for logical (control) networks are applicable to (control) networks over finite rings.

Annals of Clinical and Translational Neurology, EarlyView.ABSTRACT Objective Treatment of disorders of consciousness (DoC) remains a major clinical challenge, and noninvasive, targeted modulation of deep brain structures has emerged as a promising therapeutic strategy. We aimed to evaluate the feasibility/safety and preliminary effects of thalamic temporal interference stimulation (TIS) targeting centromedian‐

Classification of finite rings: theory and algorithm [PDF]
, 2014 summary:An interesting topic in the ring theory is the classification of finite rings. Although rings of certain orders have already been classified, a full description of all rings of a given order remains unknown.
