Metric hypergraphs and metric-line equivalences
نویسندگان
چکیده
In a metric space with distance function dist, we say that v is between u and w if u,v,w are pairwise distinct dist(u,w)=dist(u,v)+dist(v,w). All triples {u,v,w} such constitute hypergraph induced by this space. answer to question posed in [3], construct an infinite family of 3-uniform hypergraphs no The line determined pair points x y the set consisting x, y, all z one x,y,z remaining two. Two pairs said be equivalent they determine same line. resulting equivalence relation metric-line equivalence. We genuinely obstacles prevent abstract from being

Metric details of topological line-line relations
Many real and artificial entities in geographic space, such as transportation networks and trajectories of movement, are typically modeled as lines in geographic information systems. In a similar fashion, people also perceive such objects as lines and communicate about them accordingly as evidence from research on sketching habits suggests. To facilitate new modalities like sketching that rely ...
متن کاملThe metric dimension of circulant graphs and Cayley hypergraphs
Let G = (V,E) be a connected graph (or hypergraph) and let d(x, y) denote the distance between vertices x, y ∈ V (G). A subset W ⊆ V (G) is called a resolving set for G if for every pair of distinct vertices x, y ∈ V (G), there is w ∈ W such that d(x,w) 6= d(y, w). The minimum cardinality of a resolving set for G is called the metric dimension of G, denoted by β(G). In this paper we determine t...
متن کاملINTUITIONISTIC FUZZY QUASI-METRIC AND PSEUDO-METRIC SPACES
In this paper, we propose a new definition of intuitionistic fuzzyquasi-metric and pseudo-metric spaces based on intuitionistic fuzzy points. Weprove some properties of intuitionistic fuzzy quasi- metric and pseudo-metricspaces, and show that every intuitionistic fuzzy pseudo-metric space is intuitionisticfuzzy regular and intuitionistic fuzzy completely normal and henceintuitionistic fuzzy nor...

In this paper, a pointwise pseudo-metric function on the L-realline is constructed. It is proved that the topology induced by this pointwisepseudo-metric is the usual topology.
