For each natural number n, the edgeless graph (or empty graph) K n of order n is the graph with n vertices and zero edges. An edgeless graph is occasionally referred to as a null graph in contexts where the order-zero graph is not permitted. [1] [2] It is a 0-regular graph.
3. A square grid graph is a lattice graph defined from points in the plane with integer coordinates connected by unit-length edges. stable A stable set is a synonym for an independent set. star A star is a tree with one internal vertex; equivalently, it is a complete bipartite graph K 1,n for some n ≥ 2. The special case of a star with three ...
English: An empty ternary plot: i.e. 'blank graph paper' for a ternary diagram / phase diagram, with axis labels perpendicular to each plotting axis to facilitate plotting and comprehension. Arrows parallel to each side indicate direction of increase for each of the three dimensions.
A graph has a k-coloring if and only if it has an acyclic orientation for which the longest path has length at most k; this is the Gallai–Hasse–Roy–Vitaver theorem (Nešetřil & Ossona de Mendez 2012). For planar graphs, vertex colorings are essentially dual to nowhere-zero flows. About infinite graphs, much less is known.

Let be a metric space with distance function .Let be a set of indices and let () be a tuple (indexed collection) of nonempty subsets (the sites) in the space .The Voronoi cell, or Voronoi region, , associated with the site is the set of all points in whose distance to is not greater than their distance to the other sites , where is any index different from .
A graph with three components. In graph theory, a component of an undirected graph is a connected subgraph that is not part of any larger connected subgraph. The components of any graph partition its vertices into disjoint sets, and are the induced subgraphs of those sets. A graph that is itself connected has exactly one component, consisting ...
The general problem of solving Sudoku puzzles on n 2 ×n 2 grids of n×n blocks is known to be NP-complete. [8] A puzzle can be expressed as a graph coloring problem. [9] The aim is to construct a 9-coloring of a particular graph, given a partial 9-coloring. The Sudoku graph has 81 vertices, one vertex for each cell.
