Set domination in graphs

## Abstract Let __G__ = (__V, E__) be a connected graph. A set __D__ βŠ‚ __V__ is a __set‐dominating set__ (sd‐set) if for every set __T__ βŠ‚ __V__ βˆ’ __D__, there exists a nonempty set __S__ βŠ‚ __D__ such that the subgraph γ€ˆ__S__ βˆͺ __T__〉 induced by __S__ βˆͺ __T__ is connected. The set‐domination number

Domination numbers of planar graphs

The problem of determining the domination number of a graph is a well known NPhard problem, even when restricted to planar graphs. By adding a further restriction on the diameter of the graph, we prove that planar graphs with diameter two and three have bounded domination numbers. This implies that

## Abstract MacGillivray and Seyffarth (J Graph Theory 22 (1996), 213–229) proved that planar graphs of diameter two have domination number at most three and planar graphs of diameter three have domination number at most ten. They also give examples of planar graphs of diameter four having arbitrar

Independent Dominating Sets and a Second
✍ Carsten Thomassen πŸ“‚ Article πŸ“… 1998 πŸ› Elsevier Science 🌐 English βš– 241 KB

In 1975, John Sheehan conjectured that every Hamiltonian 4-regular graph has a second Hamiltonian cycle. Combined with earlier results this would imply that every Hamiltonian r-regular graph (r 3) has a second Hamiltonian cycle. We shall verify this for r 300.

## Abstract In this paper, we show that a Cayley graph for an abelian group has an independent perfect domination set if and only if it is a covering graph of a complete graph. As an application, we show that the hypercube __Q~n~__ has an independent perfect domination set if and only if __Q~n~__ i

## Abstract Let __G__ be a graph and let __S__βŠ‚__V__(__G__). We say that __S__ is __dominating__ in __G__ if each vertex of __G__ is in __S__ or adjacent to a vertex in __S__. We show that every triangulation on the torus and the Klein bottle with __n__ vertices has a dominating set of cardinality
