Fundamental relations in Ringel–Hall algebras
Journal of Algebra, 2008 Let \(A\) be a finitary \(\mathbb{F}_q\)-algebra, where \(\mathbb{F}_q\) is a finite field. Let \(\mathcal H(A)\) be the Ringel-Hall algebra of \(A\) (it is the free Abelian group with basis \(u_{[M]}\) indexed by isoclasses \([M]\) of finite dimensional \(A\)-modules \(M\); the multiplication is given by the formula \(u_{[M]}u_{[N]}=\sum_{[L]}F_{M,N ...

Computation of topological relations with 3-SRM [PDF]
Scientific ReportsTopological relation models are fundamental to spatial databases and GIS, providing a basis for reasoning about how spatial objects relate. Existing binary frameworks such as RCC-8 and the 9-Intersection Model effectively describe relations between two ...

The Fundamental Properties of Information-Carrying Relations [PDF]
, 2010 Philosophers have used information theoretic concepts and theorems for philosophical purposes since the publication of Shannon’s seminal work, “The Mathematical Theory of Communication”. The efforts of different philosophers led to the formation of Philosophy of Information as a subfield of philosophy in the late 1990s (Floridi, in press).

Commutativity and Completeness Degrees of Weakly Complete Hypergroups
Mathematics, 2022 We introduce a family of hypergroups, called weakly complete, generalizing the construction of complete hypergroups. Starting from a given group G, our construction prescribes the β-classes of the hypergroups and allows some hyperproducts not to be ...

Fundamental group and complete parts of Neutrosophic Quadruple Hv*-groups [PDF]
Neutrosophic Sets and Systems, 2023 It is well known that Hv-groups and groups are connected through regular relations. The purpose of this paper is to find a similar connection between neutrosophic Hv-groups and neutrosophic groups by using the concept of fundamental relations on Hv ...

Fundamental Relation on HvBE-Algebras
Bulletin of the Section of Logic, 2023 In this paper, we are going to introduce a fundamental relation on \(H_{v}BE\)-algebra and investigate some of properties, also construct new \((H_{v})BE\)-algebras via this relation. We show that quotient of any \(H_{v}BE\)-algebra via a regular regulation is an \(H_{v}BE\)-algebra and this quotient, via any strongly relation is a \(BE\)-algebra ...
