Hypernorm on hypervector spaces over a hyperfield

The Journal of Analysis
AbstractHypernorm is a generalization of the notion of a norm on a vector space over a field. In this paper, we consider a hypervector space $$(\mathbb {V}, +)$$ ( V , + ) over a hyperfield, where $$+

Stationary Fourier Hyperfields

Stationary Fourier Hyperfields
In this paper, we define stationary Fourier hyperfields and prove the structure theorems of stationary Fourier hyperfields. Thereby we determine the whole class of all stationary Fourier hyperfields.

Orderings and valuations in hyperfields

Journal of Algebra, 2022
We introduce and study in detail the notion of compatibility between valuations and orderings in real hyperfields. We investigate their relation with valuations and orderings induced on factor and residue hyperfields. Much of the theory from real fields can be generalized to real hyperfields; we point out facts that cannot. We generalize the Baer-Krull

Hyperhomographies on Krasner Hyperfields [PDF]

Symmetry, 2019
In this paper, we introduce generalized homographic transformations as hyperhomographies over Krasner hyperfields.These particular algebraic hyperstructues are quotient structures of classical fields modulo normal groups. Besides, we define some hyperoperations and investigate the properties of the derived hypergroups and H v -groups associated ...

Hyperfields, truncated DVRs, and valued fields [PDF]

Journal 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.
