Abstract
We prove that the strong product of any at least ${({\rm ln}}, {2})\Delta+{O}(\sqrt{\Delta})$ non‐trivial connected graphs of maximum degree at most Δ is pancyclic. The obtained result is asymptotically best possible since the strong product of ⌊(ln 2)D⌋ stars K~1,D~ is not even hamiltonian. © 2008 Wiley Periodicals, Inc. J Graph Theory 58: 314–328, 2008

## Abstract We show that the only nontrivial strongly orientable graphs for which every strong oreintation is Hamiltonian are complete graphs and cycles.
We prove that the strong product G 1 G 2 of G 1 and G 2 is Z 3 -flow contractible if and only if G 1 G 2 is not T K 2 , where T is a tree (we call T K 2 a K 4 -tree). It follows that G 1 G 2 admits an NZ 3-flow unless G 1 G 2 is a K 4 -tree. We also give a constructive proof that yields a polynomial
## Abstract We prove that the strong product of any __n__ connected graphs of maximum degree at most __n__ contains a Hamilton cycle. In particular, __G__^Δ(__G__)^ is hamiltonian for each connected graph __G__, which answers in affirmative a conjecture of Bermond, Germa, and Heydemann. © 2005 Wile
The Strong Perfect Graph Conjecture states that a graph is perfect iff neither it nor its complement contains an odd chordless cycle of size greater than or equal to 5. In this article it is shown that many families of graphs are complete for this conjecture in the sense that the conjecture is true
