On Real Hyperframes [PDF]

open access: yesJournal of Hyperstructures
The purpose of this paper is to introduce and study hyperframes. Where a frame is a generlization of a basis of a vector space, a hyperframe will act as a generalization of a basis in hypervector space.

Note on Isomorphism Theorems of Hyperrings

open access: yesInternational Journal of Mathematics and Mathematical Sciences, Volume 2010, Issue 1, 2010., 2010
There are different notions of hyperrings (R, +, ·). In this paper, we extend the isomorphism theorems to hyperrings, where the additions and the multiplications are hyperoperations.

Exact category of hypermodules

open access: yesInternational Journal of Mathematics and Mathematical Sciences, Volume 2006, Issue 1, 2006., 2006
It is shown, among other things, that the category of hypermodules is an exact category, thus generalizing the classical case.

Hyperfields, truncated DVRs, and valued fields [PDF]

open access: yesJournal of Number Theory, 2020
For any two complete discrete valued fields $K_1$ and $K_2$ of mixed characteristic with perfect residue fields, we show that if the $n$-th valued hyperfields of $K_1$ and $K_2$ are isomorphic over $p$ for each $n\ge1$, then $K_1$ and $K_2$ are isomorphic.

New building blocks for F1${\mathbb {F}}_1$‐geometry: Bands and band schemes

open access: yesJournal of the London Mathematical Society, Volume 111, Issue 4, April 2025.
Abstract We develop and study a generalization of commutative rings called bands, along with the corresponding geometric theory of band schemes. Bands generalize both hyperrings, in the sense of Krasner, and partial fields in the sense of Semple and Whittle.

Field extensions, derivations, and matroids over skew hyperfields [PDF]

open access: yes, 2018
We show that a field extension $K\subseteq L$ in positive characteristic $p$ and elements $x_e\in L$ for $e\in E$ gives rise to a matroid $M^\sigma$ on ground set $E$ with coefficients in a certain skew hyperfield $L^\sigma$.

$\lambda$-CONSTACYCLIC CODES OVER FINITE KRASNER HYPERFIELDS

open access: yesFacta Universitatis, Series: Mathematics and Informatics, 2022
The class of constacyclic codes plays an important role in the theory or error-correcting codes. They are considered as a remarkable generalization of cyclic codes.  In this paper, we study constacyclic codes over finite Krasner hyperfields in which we characterize them by their generating polynomial.
