✦ Synopsis


A set S of vertices of a graph G is a total dominating set, if every vertex of V (G) is adjacent to some vertex in S. The total domination number of G, denoted by γ t (G), is the minimum cardinality of a total dominating set of G. We prove that, if G is a graph of order n with minimum degree at least 3, then γ t (G) ≤ 7n/13.

A dominating set for a graph G = (V, E) is a subset of vertices V ⊆ V such that for all v ∈ V -V there exists some u ∈ V for which {v, u} ∈ E. The domination number of G is the size of its smallest dominating set(s). We show that for almost all connected graphs with minimum degree at least 2 and q e

The total interval number of an n-vertex graph with maximum degree ∆ is at most (∆+1/∆)n/2, with equality if and only if every component of the graph is K ∆,∆ . If the graph is also required to be connected, then the maximum is ∆n/2 + 1 when ∆ is even, but when ∆ is odd it exceeds [∆ + 1/(2.5∆ + 7.7

A total dominating function (TDF) of a graph G = (V, E) is a function f : V → [0, 1] such that for each v ∈ V , the sum of f values over the open neighbourhood of v is at least one. Zero-one valued TDFs are precisely the characteristic functions of total dominating sets of G. We study the convexity
