Neutrosophic Hyperideals of Semihyperrings [PDF]
Neutrosophic Sets and Systems, 2016 In this paper, we have introduced neutrosophic hyperideals of a semihyperring and considered some operations on them to study its basic notions and properties.

Cartesian product of intuitionistic fuzzy subgroups [PDF]
Notes on IFSFuzzy sets have become fundamental tools for addressing uncertainty and ambiguity across a wide range of scientific disciplines. A significant development within fuzzy set theory is the emergence of fuzzy subgroups, which adapt fuzzy set principles to ...

On density of subgraphs of Cartesian products [PDF]
Journal of Graph Theory, 2019 AbstractIn this paper, we extend two classical results about the density of subgraphs of hypercubes to subgraphs of Cartesian products of arbitrary connected graphs. Namely, we show that , where is the maximum ratio taken over all subgraphs of .

Subtraction Menger algebras [PDF]
, 2010 characterizations of Menger algebras of partial $n$-place functions defined on a set $A$ and closed under the set-theoretic difference functions treatment as subsets of the Cartesian product $A^{n+1}$ are ...

Edge-Transitive Lexicographic and Cartesian Products
Discussiones Mathematicae Graph Theory, 2016 In this note connected, edge-transitive lexicographic and Cartesian products are characterized. For the lexicographic product G ◦ H of a connected graph G that is not complete by a graph H, we show that it is edge-transitive if and only if G is edge ...

New Results on the Aggregation of Norms
Mathematics, 2021 It is a natural question if a Cartesian product of objects produces an object of the same type. For example, it is well known that a countable Cartesian product of metrizable topological spaces is metrizable.

Convex polygons in cartesian products
Journal of Computational Geometry, 2018 We study several problems concerning convex polygons whose vertices lie in a Cartesian product of two sets of $n$ real numbers (for short, \emph{grid}). First, we prove that every such grid contains $\Omega(\log n)$ points in convex position and that this bound is tight up to a constant factor.

On Cartesian Products of Signed Graphs [PDF]
Discrete Applied Mathematics, 2020 In this paper, we study the Cartesian product of signed graphs as defined by Germina, Hameed and Zaslavsky (2011). Here we focus on its algebraic properties and look at the chromatic number of some Cartesian products. One of our main results is the unicity of the prime factor decomposition of signed graphs.

Motion planning in cartesian product graphs
Discussiones Mathematicae Graph Theory, 2014 Let G be an undirected graph with n vertices. Assume that a robot is placed on a vertex and n − 2 obstacles are placed on the other vertices. A vertex on which neither a robot nor an obstacle is placed is said to have a hole.
