Closure properties for fitting functors

Monatshefte f�r Mathematik, 1989
Fitting functors have been introduced by \textit{B. Brewster} and the present authors [Math. Z. 182, 359-384 (1983; Zbl 0518.20014)] as a generalization of injectors and radicals for Fitting classes of finite (soluble) groups. This paper provides definitions and properties of certain types of Fitting functors which resemble injectors and radicals for ...

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.

P-CLOSURE IN PSEUDO BCI-ALGEBRAS [PDF]

Journal of Algebraic Systems, 2020
In this paper, for any non-empty subset C of a pseudo BCI-algebra X, the concept of p-closure of C, denoted by C(pc), is introduced and some related properties are investigated.

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.

Influence of the Production Process on the Binding Mechanism of Clinched Aluminum Steel Mixed Compounds

Journal of Manufacturing and Materials Processing, 2021
The multi-material design and the adaptability of a modern process chain require joining connections with specifically adjustable mechanical, thermal, chemical, or electrical properties.

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 ...

Ordering Awad–Varma Entropy and Applications to Some Stochastic Models

Mathematics, 2021
We consider a generalization of Awad–Shannon entropy, namely Awad–Varma entropy, introduce a stochastic order on Awad–Varma residual entropy and study some properties of this order, like closure, reversed closure and preservation in some stochastic ...
