TLDR
A new axiom is introduced: for any x,y,z, R(x,y) = x, y = Rightarrow y in R (x,z) or x in R(y,Z) for any \( x,Y,z \in V\),
Abstract
The axiomatic approach with the interval function and induced path transit function of a connected graph is an interesting topic in metric and related graph theory. In this paper, we introduce a new axiom: (bp) for any \( x,y,z \in V\), \(R(x,y)=\{x,y\} \Rightarrow y\in R(x,z)\) or \(x\in R(y,z)\).

The induced paths in a connected graph and a ternary relation determined by them

TL;DR: In this paper, it was shown that there is no sentence σ of the first-order logic such that a ternary structure (X0, T0) with a connected underlying graph G is the B-structure of G if and only if σ satisfies σ.

A Characterization of the Interval Function of a (Finite or Infinite) Connected Graph

TL;DR: In this article, the authors give a characterization of the interval function of each connected graph, which is very important for studying properties of a finite connected graph which depend on the distance between vertices.

The induced path function, monotonicity and betweenness

TL;DR: In this article, the authors considered the problem of axiomatic characterizations of the induced path function J of a connected graph G. This function is a special instance of a transit function.
