On secure domination in trees

open access: yesQuaestiones Mathematicae, 2017
A subset D of the vertex set of a graph G is a secure dominating set of G if D is a dominating set of G and if, for each vertex u not in D, there is a vertex v in D adjacent to u such that the swap set (D \ {v}) {u} is again a dominating set of G.

The security number of lexicographic products

open access: yesQuaestiones Mathematicae, 2018
A subset S of vertices of a graph G is a secure set if |N[X] ∩ S| ≥ |N[X]−S| holds for any subset X of S, where N[X] denotes the closed neighborhood of X. The minimum cardinality s(G) of a secure set in G is called the security number of G.
