The second largest number of maximum independent sets in trees of odd order without duplicated leaves

Applied Mathematical Sciences, 2021
In a graph G = (V,E), an independent set is a subset I of V (G) such that no two vertices in I are adjacent. A maximum independent set is an independent set of maximum size.

Trees with the total domination number twice the distance-2 domination number

, 2021
The distance between two vertices u and v in a graph equals the length of a shortest path from u to v. The distance-2 domination number of a graph G, denoted by γ2(G), is the minimum cardinality of a vertex subset where every vertex not belonging to the ...
