On the borderline of fields and hyperfields, part Ⅱ – Enumeration and classification of the hyperfields of order 7

open access: yesAIMS Mathematics
127 pages, 305 tables Subj-class: math.RA - Rings and Algebras MSC-class: 16Y20 (Primary); 20N20 (Secondary) We extend the results of our previous papers and we reduce the axioms of the definition of the hyperfield. This facilitates the construction, enumeration and classification of all the hyperfields of order 7, while also revealing an important ...

THE CLASS OF KRASNER HYPERFIELDS IS NOT ELEMENTARY [PDF]

open access: yesThe Journal of Symbolic Logic
Abstract We show that the class of Krasner hyperfields is not elementary. To show this, we determine the rational rank of quotients of multiplicative groups in field extensions. We also discuss some related questions.

Small weak hyperfields in hadronic mechanics

open access: yesRatio Mathematica
It was in mid 90es when Professor R. M. Santilli realized, for the first time, that his innovating theories can be appropriate expressed by multi-valued systems.

On the hyperfields associated to valued fields

open access: yesJournal of Pure and Applied Algebra
One can associate to a valued field an inverse system of valued hyperfields $(\mathcal{H}_i)_{i \in I}$ in a natural way. We investigate when, conversely, such a system arise from a valued field. First, we extend a result of Krasner by showing that the inverse limit of certain systems are stringent valued hyperfields.

Quadratic structures associated to (multi)rings [PDF]

open access: yesCategories and General Algebraic Structures with Applications, 2022
We consider certain pairs (A, T) where A is a (multi)ring andT ⊆ A is a multiplicative set that generates, by a convenient quotient construction,a (multi)structure that supports a quadratic form theory: withsome natural hypotheses we generalize ...

K-theories and Free Inductive Graded Rings in Abstract Quadratic Forms Theories [PDF]

open access: yesCategories and General Algebraic Structures with Applications, 2022
We build on previous work on multirings ([17]) that providesgeneralizations of the available abstract quadratic forms theories (specialgroups and real semigroups) to the context of multirings ([10], [14]).

ϕ ‐δ‐Primary Hyperideals in Krasner Hyperrings

open access: yesMathematical Problems in Engineering, Volume 2022, Issue 1, 2022., 2022
In this paper, we study commutative Krasner hyperrings with nonzero identity. ϕ‐prime, ϕ‐primary and ϕ‐δ‐primary hyperideals are introduced. The concept of δ‐primary hyperideals is extended to ϕ‐δ‐primary hyperideals. Some characterizations of hyperideals are provided to classify them.

On 1‐Absorbing Prime Hyperideal and Some of Its Generalizations

open access: yesJournal of Mathematics, Volume 2022, Issue 1, 2022., 2022
In this paper, we introduce the concept of 1‐absorbing prime hyperideals which is an expansion of the prime hyperideals. Several properties of the hyperideals are provided. For example, it is proved that if a strong C‐hyperideal I of R is 1‐absorbing prime that is not prime, then R is a local multiplicative hyperring.

[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.

Valuations on Structures More General Than Fields

open access: yesComputer Sciences & Mathematics Forum, 2023
Valuation theory is an important area of investigation in algebra, with applications in algebraic geometry and number theory. In 1957, M. Krasner introduced hyperfields, which are field-like objects with a multivalued addition, to describe some ...
