Helly Number, Radon Number and Rank in -Convexity on Graphs
Bijo S Anand, Arun Anil, Manoj Changat +2
This article discusses -convexity on simple connected graphs. We establish general bounds for the Helly number, Radon number, and rank with respect to -convexity on graphs. A…
The Median of Sierpinski Triangle Graphs
Kannan Balakrishnan, Manoj Changat, M V. Dhanyamol +3
The median of a graph is the set of vertices with a minimum total distance to all other vertices in the graph. In this paper, we determine the median of Sierpiński triangle…
Directed Transit Functions
Arun Anil, Manoj Changat, Lekshmi Kamal K-Sheela +5
Transit functions were introduced as models of betweenness on undirected structures. Here we introduce directed transit function as the directed analogue on directed structures suc…
Convex Geometries yielded by Transit Functions
Manoj Changat, Lekshmi Kamal K. Sheela, Iztok Peterin +1
Let be a finite nonempty set. A transit function is a map such that , and hold for every . A…
Weakly modular graphs with diamond condition, the interval function and axiomatic characterizations
Lekshmi Kamal Kamalolbhavan-Sheela, Jeny Jacob, Manoj Changat
Weakly modular graphs are defined as the class of graphs that satisfy the \emph{triangle condition ()} and the \emph{quadrangle condition ()}. We study an interesting subcl…
