Revisiting the outer-weakly convex domination number in graph products

Bijo S. Anand, Ullas Chandran S. V., Jonecis A. Dayap +2

Let be a simple undirected connected graph. A set is weakly convex in if for every two vertices in , there exists a geodesic whos…

Partitions and covers in convexity

Bijo S. Anand, Manoj Changat, Mitre C. Dourado +2

Given a graph and a set , we say that is -convex if the neighborhood of every vertex not in is an independent set. A collection ${\cal V} = (V_1,…

Boundary vertices of Strongly Connected Digraphs with respect to `Sum Metric'

Bijo S. Anand, Manoj Changat, Prasanth G. Narasimha-Shenoi +3

Suppose is a strongly connected digraph and . Among the many metrics in graphs, the sum metric warrants further exploration. The sum distance $sd(u, v)…
