In particular, we completely determine the game chromatic number of the …
Graph strong product
Did you know?
In graph theory, a graph product is a binary operation on graphs. Specifically, it is an operation that takes two graphs G1 and G2 and produces a graph H with the following properties: • The vertex set of H is the Cartesian product V(G1) × V(G2), where V(G1) and V(G2) are the vertex sets of G1 and G2, respectively. • Two vertices (a1,a2) and (b1,b2) of H are connected by an edge, iff a condition about a1, b1 in G1 and a2, b2 in G2 is fulfilled.

The connectivity of a simple graph G = ( V ( G), E ( G)) is the number, denoted as κ ( G), equal to the fewest number of vertices whose removal from G results in a disconnected or trivial graph. The Cartesian product of graphs G and H is the graph G H with vertices V ( G H) = V ( G) × V ( H), and for which ... WebApr 19, 2024 · in general.
