Some Types of Filters in Equality Algebras [PDF]

open access: yesCategories and General Algebraic Structures with Applications, 2017
Equality algebras were introduced by S. Jenei as a possible algebraic semantic for fuzzy type theory. In this paper, we introduce some types of filters such as (positive) implicative, fantastic, Boolean, and prime filters in equality algebras and we ...

Commutative Pseudo Valuations on BCK-Algebras

open access: yesInternational Journal of Mathematics and Mathematical Sciences, 2011
The notion of a commutative pseudo valuation on a BCK-algebra is introduced, and its characterizations are investigated. The relationship between a pseudo valuation and a commutative pseudo-valuation is examined.

Hyperbolicity and fundamental groups of complex quasi‐projective varieties (III): Applications

open access: yesProceedings of the London Mathematical Society, Volume 133, Issue 5, November 2026.
Abstract This paper is Part III of a series of three. We begin by introducing the notion of h$h$‐special varieties, which can be seen as varieties “chain‐connected by the Zariski closures of entire curves.” We prove that if X$X$ is either a special smooth complex quasi‐projective variety in the sense of Campana or an h$h$‐special variety, then for any ...

Hidden constructions in abstract algebra: Krull dimension of distributive lattices and commutative rings

open access: yes, 2003
We present constructive versions of Krull's dimension theory for commutative rings and distributive lattices. The foundations of these constructive versions are due to Joyal, Espanol and the authors.

Workshop on Commutative Algebra

open access: yes, 1990
The central theme of this volume is commutative algebra, with emphasis on special graded algebras, which are increasingly of interest in problems of algebraic geometry, combinatorics and computer algebra.

On the range of completely bounded maps

open access: yesInternational Journal of Mathematics and Mathematical Sciences, 1978
It is shown that if every bounded linear map from a C*-algebra α to a von Neumann algebra β is completely bounded, then either α is finite-dimensional or β⫅𝒞⊗Mn, where 𝒞 is a commutative von Neumann algebra and Mn is the algebra of n×n complex matrices.

Odd and even derivations, transposed Poisson superalgebra and 3-Lie superalgebra [PDF]

open access: yesProceedings of the Estonian Academy of Sciences
One important example of a transposed Poisson algebra can be constructed by means of a commutative algebra and its derivation. This approach can be extended to superalgebras; that is, one can construct a transposed Poisson superalgebra given a ...

Discrete homotopy hypothesis for n$n$‐types

open access: yesProceedings of the London Mathematical Society, Volume 133, Issue 5, November 2026.
Abstract We show that discrete and classical homotopy theories are equivalent after localizing at n$n$‐equivalences for any non‐negative integer n$n$. By constructing an explicit homotopy inverse to the graph nerve functor associating an n$n$‐fibrant cubical set to a graph, we are also able to give explicit computations of several previously unknown ...

On the description and identifiability analysis of experiments with mixtures [PDF]

open access: yes, 2006
In a mixture experiment the collinearity problems, implied by the sum to one functional relationship among the factors, have strong consequences on the identification and analysis of regression models for such designs.

Signature-based algorithm on non-commutative rings and its implementation (Computer Algebra - Theory and its Applications)

open access: yes, 2021
Signature-based algorithm is an algorithm for computing Gröbner bases over polynomial ring. In this paper, we give the non-commutative theory of minimal signature and the non-commutative signature-based algorithm on both Weyl algebra and Poincaré ...
