A Novel Study on Ordered Anti‐Involution LA‐Semihypergroups

open access: yesJournal of Mathematics, Volume 2023, Issue 1, 2023., 2023
In this study, we introduce a new concept called “anti‐involution” in relation to ordered LA‐semihypergroups. An anti‐involution is basically an involuntary automorphism, which is just a fancy term for a mathematical function that can be reversed. We looked at several fundamental results before introducing anti‐involution hyperideals.

[Retracted] Roughness in Hypervector Spaces

open access: yesJournal of Function Spaces, Volume 2022, Issue 1, 2022., 2022
This paper examines rough sets in hypervector spaces and provides a few examples and results in this regard. We also investigate the congruence relations‐based unification of rough set theory in hypervector spaces. We introduce the concepts of lower and upper approximations in hypervector spaces.

The Lattice Structures of Approximation Operators Based on L‐Fuzzy Generalized Neighborhood Systems

open access: yesComplexity, Volume 2021, Issue 1, 2021., 2021
Following the idea of L‐fuzzy generalized neighborhood systems as introduced by Zhao et al., we will give the join‐complete lattice structures of lower and upper approximation operators based on L‐fuzzy generalized neighborhood systems. In particular, as special approximation operators based on L‐fuzzy generalized neighborhood systems, we will give the

Unitless Frobenius Quantales

open access: yesApplied Categorical Structures, 2022
It is often stated that Frobenius quantales are necessarily unital. By taking negation as a primitive operation, we can define Frobenius quantales that may not have a unit. We develop the elementary theory of these structures and show, in particular, how to define nuclei whose quotients are Frobenius quantales.

Quantal microbiology [PDF]

open access: yesLetters in Applied Microbiology, 2000
Quantal microbiology describes a similarity between physics and microbiology. In both sciences there is an apparent dichotomy between the certainty and stability of the macro-subject and the uncertainty/complexity of the individual atom/cell. Classical physics is to quantum mechanics as classical microbiology is to quantal microbiology.

Reflectors to quantales

open access: yesFuzzy Sets and Systems, 2023
In this paper, we show that marked quantales have a reflection into quantales. To obtain the reflection we construct free quantales over marked quantales using appropriate lower sets. A marked quantale is a posemigroup in which certain admissible subsets are required to have joins, and multiplication distributes over these. Sometimes are the admissible

Propositional Logics for the Lawvere Quantale [PDF]

open access: yes, 2023
Lawvere showed that generalised metric spaces are categories enriched over $[0, \infty]$, the quantale of the positive extended reals. The statement of enrichment is a quantitative analogue of being a preorder.

Convolution Algebras: Relational Convolution, Generalised Modalities and Incidence Algebras [PDF]

open access: yesLogical Methods in Computer Science, 2021
Convolution is a ubiquitous operation in mathematics and computing. The Kripke semantics for substructural and interval logics motivates its study for quantale-valued functions relative to ternary relations. The resulting notion of relational convolution

New characterization theorems of the mp-quantales [PDF]

open access: yesJournal of Fuzzy Extension and Applications, 2021
The mp-quantales were introduced in a previous paper as an abstraction of the lattices of ideals in mp-rings and the lattices of ideals in conormal lattices. Several properties of m-rings and conormal lattices were generalized to mp-quantales.

Local T0 and T1 quantale valued preordered spaces

open access: yes, 2022
Bu tez çalışmasının temel amacı quantale değerli önsıralı uzaylar kategorisinde bir p noktasında T0 ve T1 objeleri karakterize ederek arasındaki ilişkiyi araştırmak ve bu objelerin kalıtsal ve çarpımsal olup olmadıklarını incelemektir.
