Transitive Closure of Interval-valued Fuzzy Relations [PDF]

International Journal of Computational Intelligence Systems, 2013
In this paper are introduced some concepts of interval-valued fuzzy relations and some of their properties: reflexivity, symmetry, T-transitivity, composition and local reflexivity.

On Operations over Language Families [PDF]

Computer Science Journal of Moldova, 2019
Let $O$ and $\F$ be an operation and a language family, respectively. So far, in terms of closure properties, the classical language theory has only investigated whether $O(\F) \subseteq \F$, where $O(\F)$ is the family resulting from $O$ applied to all ...

Some Unitary Operators on Hoop-algebras

Fuzzy Information and Engineering, 2017
In this paper, we introduce the notions of multiplier, ⊙-closure operator and modal operator on hoop-algebras. After that, we investigate some algebraic properties of multiplier, ⊙-closure operator and modal operator on hoop-algebras.

On θω continuity

Heliyon, 2020
We use the closure and the theta omega closure operators to introduce θω-continuous, ω-θ-continuous, weakly θω-continuous and faintly θω-continuous as new four classes of functions.

A Novel Subclass of Harmonic Functions: Coefficient Bounds, Distortion Bounds, and Closure Properties

Sakarya Üniversitesi Fen Bilimleri Enstitüsü Dergisi
In this paper, we introduce a new subclass of harmonic functions that significantly improves our understanding of these functions in geometric function theory. We provide a comprehensive analysis of this subclass by deriving several important properties,

All about unambiguous polynomial closure [PDF]

TheoretiCS
We study a standard operator on classes of languages: unambiguous polynomial closure. We prove that for every class C of regular languages satisfying mild properties, the membership problem for its unambiguous polynomial closure UPol(C) reduces to the ...
