On n-fold fuzzy implicative/commutative ideals of BCK-algebras [PDF]

International Journal of Mathematics and Mathematical Sciences, 2001
We consider the fuzzification of the notion of an n-fold implicative ideal, an n-fold (weak) commutative ideal. We give characterizations of an n-fold fuzzy implicative ideal. We establish an extension property for n-fold fuzzy commutative ideals.

An exotic characterization of a commutative H*-algebra [PDF]

International Journal of Mathematics and Mathematical Sciences, 2000
Commutative H*-algebra is characterized in terms of the property that the orthogonal complement of a right ideal is a left ideal.

The Structure of Semiconic Idempotent Commutative Residuated Lattices

Mathematics
In this paper, we study semiconic idempotent commutative residuated lattices. After giving some properties of such residuated lattices, we obtain a structure theorem for semiconic idempotent commutative residuated lattices. As an application, we make use

An Introduction to i-Commutative Rings

Mathematics
In this paper, we introduce a new class of rings, called i-commutative rings, by extending the concept of commutative-like rings using idempotent elements.

Operads and Γ-homology of commutative rings [PDF]

, 2002
We introduce Γ-homology, the natural homology theory for E[infty infinity]-algebras, and a cyclic version of it. Γ-homology specializes to a new homology theory for discrete commutative rings, very different in general from André–Quillen homology.

Spectral Extension Property of Perturbed Triple Product on Semisimple Commutative Banach Algebras [PDF]

, 2022
Under a perturbed triple product defined on three semisimple commutative Banach algebras with the influence of two homomorphisms defined on two of them and that carry certain characteristics, we proved that the spectral extension property is ...

Every commutative JB∗‑triple satisfies the complex Mazur–Ulam property [PDF]

, 2022
We prove that every commutative JB*-triple, represented as a space of continuous functions C-0(T)(L), satisfies the complex Mazur-Ulam property, that is, every surjective isometry from the unit sphere of C-0(T)(L) onto the unit sphere of any complex ...

Enumeration of Involutions of Finite Rings

Journal of New Theory, 2021
In this paper, we study a special class of elements in the finite commutative rings called involutions. An involution of a ring R is an element with the property that x^2-1=0 for some x in R.

Efficient Computation of Intervention in Causal Bayesian Networks [PDF]

Jisuanji kexue, 2022
In causal Bayesian networks (CBNs),it is a fundamental problem to compute the causal effect of sum product.From the perspective of a directed acyclic graph,we show every CBN has a corresponding Bayesian network.Intervention is a fundamental operation in ...

Local Uniform Convexity and Kadec-Klee Type Properties in K-interpolation spaces II

Journal of Function Spaces and Applications, 2004
We study local uniform convexity and Kadec-Klee type properties in K-interpolation spaces of Lorentz couples. We show that a wide class of Banach couples of (commutative and) non-commutative Lorentz spaces possess the (so-alled) (DGL)-property originally
