On Gray Images of Cyclic and Self-Orthogonal Codes over Fq+uFq+vFq [PDF]

open access: yesEntropy
Let p be a prime with p∉{2,5} and let q=pm. This paper studies cyclic and self-orthogonal linear codes of length n over the finite local non-Frobenius ring Rp,u,v=Fq+uFq+vFq, u2=v2=uv=vu=0.

On Almost Quasi-Frobenius Fuzzy Rings

open access: yesمجلة بغداد للعلوم, 2004
In this paper, we introduce the concept of almost Quasi-Frobcnius fuzzy ring as a " " of Quasi-Frobenius ring. We give some properties about this concept with qoutient fuzzy ring. Also, we study the fuzzy external direct sum of fuzzy rings.

Frobenius splitting of Schubert varieties of semi-infinite flag manifolds

open access: yesForum of Mathematics, Pi, 2021
We exhibit basic algebro-geometric results on the formal model of semi-infinite flag varieties and its Schubert varieties over an algebraically closed field ${\mathbb K}$ of characteristic $\neq 2$ from scratch.

A Generalization of Quasi-Frobenius Rings [PDF]

open access: yesProceedings of the American Mathematical Society, 1969
Let \(R\) be a ring and \(_R\mathcal M\) the category of all left \(R\)-modules. \textit{G. Azumaya} [Nagoya Math. J. 27, 697--708 (1966; Zbl 0144.02303)] proved that if all faithful left \(R\)-modules are generators in \(_R\mathcal M\), \(R\) is left self-injective and a direct sum of indecomposable left ideals having minimal left ideals (cf.

Some results on quasi-Frobenius rings [PDF]

open access: yesCommentationes Mathematicae Universitatis Carolinae, 2017
Summary: We give some new characterizations of quasi-Frobenius rings by the generalized injectivity of rings. Some characterizations give affirmative answers to some open questions about quasi-Frobenius rings, and some characterizations improve some results on quasi-Frobenius rings.

Filtered quasi-Frobenius rings

open access: yesMathematische Zeitschrift, 1968
The main object of this note is to prove that a filtered ringA is quasi-Frobenius, if its associated graded ring E ~ (A) is quasi-Frobenius (Theorem 1). In w 1, we discuss some generalities on quasi-Frobenius rings. In w 2, given a filtered ring A such that F~A=A for some n, we construct an injective, filtered Amodule F* such that E ~ (F*) is E ~ (A ...

Quasi-Frobenius quotient rings of group rings [PDF]

open access: yesJournal of the Australian Mathematical Society, 1975
The purpose of this paper is an extension of a theorem of Hughes (1973). He showed: Let R be a ring which has a right artinian right quotient ring and let G be a group which has a (transfinite) ascending normal series with each factor either finite or cyclic, but only a finite number of finite factors.

A note on quasi-Frobenius rings [PDF]

open access: yesProceedings of the American Mathematical Society, 1996
It is shown that a semiperfect ring R R is quasi-Frobenius if and only if every closed submodule of R ( ω ) R(\omega ) is non-small, where R ( ω ) R(\omega ) denotes the direct sum of ω \omega copies of the right ...
