On Domatic and Total Domatic Numbers of Cartesian Products of Graphs

Bulletin of the Malaysian Mathematical Sciences Society, 2023
A domatic \(k\)-coloring of a simple, undirected graph \(G\) is an assignment of \(k\) colors to the vertices of \(G\) such that each vertex contains vertices of all \(k\) colors in its closed neighborhood. The domatic number of \(G\), denoted \(d(G)\), is the maximum \(k\) for which \(G\) has a domatic \(k\)-coloring. A total domatic \(k\)-coloring is

Approximating the domatic number

Proceedings of the thirty-second annual ACM symposium on Theory of computing, 2000
A set of vertices in a graph is a dominating set if every vertex outside the set has a neighbor in the set. The domatic number problem is that of partitioning the vertices of a graph into the maximum number of disjoint dominating sets. Let n denote the number of vertices, δ the minimum degree, and ∆ the maximum degree.

Fractional Domatic, Idomatic, and Total Domatic Numbers of a Graph

2020
The fractional domatic number of a graph G is the maximum ratio \(|\mathcal {F}|/m(\mathcal {F})\) over all families \(\mathcal {F}\) of dominating sets of G, where \(m(\mathcal {F})\) denotes the maximum number of times any particular vertex appears in \(\mathcal {F}\).

GRAPHS THAT ARE NOT DOMATICALLY CO-CRITICAL

Discrete Mathematics, Algorithms and Applications, 2011
A graph G is said to be domatically co-critical, if d(G + uv) > d(G), for any two non-adjacent vertices u, v in G. In this paper we present the set of graphs that are not domatically co-critical.

On the domatic number of internal graphs

Information Processing Letters, 1988
A dominating set of a graph G is a subset S of the nodes such that every node of G is either in S or adjacent to some node in S. The domatic number of G is the size of a maximum cardinality partition of the nodes into dominating sets. We present an \(O(n^{2.5})\) time algorithm for finding the domatic number, as well as the desired partition, of an ...
