A note on Hypervector Spaces

open access: yes, 2020
The main aim of this paper is to generalize the concept of vector space by the hyperstructure. We generalize some definitions such as hypersubspaces, linear combination, Hamel basis, linearly dependence and linearly independence.

Notes on valuation theory for Krasner hyperfields

open access: yes, 2023
The main aim of this article is to study and develop valuation theory for Krasner hyperfields. In analogy with classical valuation theory for fields, we generalise the formalism of valuation rings to describe equivalence of valuations on hyperfields ...

Convex geometry over ordered hyperfields

open access: yesInnovations in Incidence Geometry: Algebraic, Topological and Combinatorial
We initiate the study of convex geometry over ordered hyperfields. We define convex sets and halfspaces over ordered hyperfields, presenting structure theorems over hyperfields arising as quotients of fields. We prove hyperfield analogues of Helly, Radon and Carathéodory theorems. We also show that arbitrary convex sets can be separated via hemispaces.

Root selections and 2^p-th root selections in hyperfields

open access: yesDiscussiones Mathematicae - General Algebra and Applications, 2019
In this paper we define root selections and 2p-th root selections for hyperfields: these are multiplicative subgroups whose existence is equivalent to the existence of a well behaved square root function and 2p-th root function, respectively. We proceed to investigate some basic properties of such root selections, and draw some parallels between the ...

Linear algebra over T-pairs

open access: yes, 2023
Preprint arXiv:2310.05257This paper treats linear algebra over a semiring pair, in a wide range of applications to tropical algebra and related areas such as hyperrings and fuzzy rings.

Sur les hypergroupes polysymétriques commutatifs

open access: yes, 1986
Si presenta un breve studio di ipergruppi polisimmetrici (risultati dalla considerazione di matrici con elementi tratti da un ipercorpo [2], [7], [11]) nel caso commutativo.

Matroids over tropical extensions of tracts

open access: yes
A tract $F$ is an algebraic structure where multiplication is defined but addition is only partially defined. They were introduced by Baker and Bowler as a unified framework to study generalisations of matroids, including oriented and valuated matroids ...
