Towards a generalisation of formal concept analysis for data mining purposes [PDF]
, 2006 In this paper we justify the need for a generalisation of Formal Concept Analysis for the purpose of data mining and begin the synthesis of such theory.

Journal of Function Spaces, Volume 2019, Issue 1, 2019., 2019 The aim of this paper is to generalize the Choquet‐like integral with respect to a nonmonotonic fuzzy measure for generalized real‐valued functions and set‐valued functions, which is based on the generalized pseudo‐operations and σ‐⊕‐measures. Furthermore, the characterization theorem and transformation theorem for the integral are given.

Ordered Quasi(BI)‐Γ‐Ideals in Ordered Γ‐Semirings
Journal of Mathematics, Volume 2019, Issue 1, 2019., 2019 In this paper, we have defined ordered quasi‐Γ‐ideals and ordered bi‐Γ‐ideals in ordered Γ‐semirings by defining the relation “≤” in ordered Γ semiring S as a ≤ b if a + x = b for any a, b, x ∈ S. By using this relation we have shown that ordered quasi‐Γ‐ideals and ordered bi‐Γ‐ideals in ordered Γ‐semirings are generalization of quasi‐ideals and bi ...

Simplices in the Endomorphism Semiring of a Finite Chain
Algebra, Volume 2014, Issue 1, 2014., 2014 We establish new results concerning endomorphisms of a finite chain, if the cardinality of the image of such endomorphism is no more than some fixed number. The semiring of all such endomorphisms can be seen as a simplex whose vertices are the constant endomorphisms. We explore the properties of these simplices.

Right k‐Weakly Regular Γ‐Semirings
Algebra, Volume 2014, Issue 1, 2014., 2014 The concepts of a k‐idempotent Γ‐semiring, a right k‐weakly regular Γ‐semiring, and a right pure k‐ideal of a Γ‐semiring are introduced. Several characterizations of them are furnished.

On Exact Sequence of Semimodules over Semirings
International Scholarly Research Notices, Volume 2013, Issue 1, 2013., 2013 We introduce the notion of exact sequence of semimodules over semirings using maximal homomorphisms and generalize some results of module theory to semimodules over semirings. Indeed, we prove, “If 00→L→fM→gN→ is a split exact sequence of R‐semimodules and maximal R‐semimodule homomorphisms with Ker(g) is a strong subsemimodule of M, then M≅L ⊕ N ...

, 2017 In this paper, we provide a complete description of congruence-semisimple semirings and introduce the pre-ordered abelian Grothendieck groups $K_0(S)$ and $SK_0(S)$ of the isomorphism classes of the finitely generated projective and strongly projective S-

On quasi‐ideals and bi‐ideals in ternary semirings
International Journal of Mathematics and Mathematical Sciences, Volume 2005, Issue 18, Page 3015-3023, 2005., 2005 We introduce the notions of quasi‐ideal and bi‐ideal in ternary semirings and study some properties of these two ideals. We also characterize regular ternary semiring in terms of these two subsystems of ternary semirings.

Derivatives of triangular, Toeplitz, circulant matrices and matrices of other forms over semirings
, 2017 In this article we construct examples of derivations in matrix semirings. We study hereditary and inner derivations, derivatives of diagonal, triangular, Toeplitz, circulant matrices and of matrices of other forms and prove theorems for derivatives of ...
