Suppose G and H are graphs. We say G is H-colorable if there is a homomorphism (edge-preserving vertex mapping) from G to H. We say a graph G is uniquely H-colorable if there is an onto homomorphism c from G to H, and any other homomorphism from G to H is the composition o o c of c with an automorph

The game of cops and robbers is played with a set of 'cops' and a 'robber' who occupy some vertices of a graph. Both sides have perfect information and they move alternately to adjacent vertices. The robber is captured if at least one of the cops occupies the same vertex as the robber. The problem i
## Abstract For any __d__β©Ύ5 and __k__β©Ύ3 we construct a family of Cayley graphs of degree __d__, diameter __k__, and order at least __k__((__d__β3)/3)^__k__^. By comparison with other available results in this area we show that our family gives the largest currently known Cayley graphs for a wide ra
We show that every n-vertex cubic graph with girth at least g have domination number at most 0.299871n+O(n / g) < 3n / 10+O(n / g) This research was done when the Petr Ε koda was a student of
