We show that the theory of hyperrings, due to M. Krasner, supplies a perfect framework to understand the algebraic structure of the adèle class space HK = AK/K of a global field K. After promoting F1 to a hyperfield K, we prove that a hyperring of the form R/G (where R is a ring and G ⊂ R× is a subgroup of its multiplicative group) is a hyperring extension of K if and only if G ∪ {0} is a subfi...

This paper considers the relations among L -fuzzy sets, rough sets and hyperring theory. Based on a complete residuated lattice, the concept of (invertible) L-fuzzy hyperideals of a hyperring is introduced and some related properties are presented. The notions of lower and upper L-fuzzy rough approximation operators with respect to an L-fuzzy hyperideal are provided and some significant propert...

The development of spatial data infrastructures (SDIs) aims to promote environmental management. However, technological advances, organizational and regulatory frameworks available do not seem sufficient for the realization of such an objective. For many authors, the real contribution of SDIs depends on the answers they provide to their users. This paper presents an original methodological appr...

In this paper, our aim is to generalize and extend the Hopkins-Levitzki theorem from noncommutative rings Krasner hyperring. Also, we prove that a hyperring R Noetherian if only it satisfies ascending chain conditions of prime hyperideals.

A class of hyperrings known as divisible will be studied in this paper. It presented each element hyperring is a element. Also shows the relationship between Jacobsen Radical, and set invertible elements gets some results, linked these results with hyperring. After going through concept hypermodule that by Sopon Boriboon Sajee Pianskool 2017, later 2022 Hashem Bordbar, Irina Cristea, related to...

This paper addresses the need for capacity building for using GIS and building spatial data infrastructures (SDIs) in South-East Europe. This is a recognized need, which is dealt with, amongst others, by the European project eSDI-NET+ that has build a network of users and key European SDI stakeholders in Europe to share experiences and best practices. Using a detailed assessment methodology for...

In the theory of hyperrings, fundamental relations make a connection between hyperrings and ordinary rings. Commutative fundamental rings and the fundamental relation α which is the smallest strongly regular relation in hyperringswere introduced by Davvaz and Vougiouklis (2007). Recently, another strongly regular relation named θ on hyperrings has been studied by Ameri and Norouzi (2013). Ameri...

Let G be a group (monoid) with identity e and R commutative Krasner hyperring. In this paper, we introduce the concepts of graded absorbing hyperideals hyperring such as, 2-absorbing hyperideals, n-absorbing subhypermodules. Some basic properties these structures characterizations homogeneous components are proved.

This survey article presents some recent results in the theory of hyperfields and hyperrings, algebraic structures for which the "sum" of two elements is a subset of the structure. The results in this paper show that these structures .cannot always be embedded in the decomposition of an ordinary structure (ring or field) in equivalence classes and that the structural results for hyperfields and...
