2. Edge coloring - Wikipedia

   en.wikipedia.org/wiki/Edge_coloring

   A conjecture of Claude Berge and D. R. Fulkerson that the 6-regular multigraphs formed by doubling every edge of a bridgeless 3-regular simple graph may be edge-colored with six colors. A conjecture of Fiorini and Wilson that every triangle-free planar graph, other than the claw K 1,3, is not uniquely 3-edge-colorable.

3. Molecular graph - Wikipedia

   en.wikipedia.org/wiki/Molecular_graph

   In some important cases (topological index calculation etc.) the following classical definition is sufficient: a molecular graph is a connected, undirected graph which admits a one-to-one correspondence with the structural formula of a chemical compound in which the vertices of the graph correspond to atoms of the molecule and edges of the ...

4. Havel–Hakimi algorithm - Wikipedia

   en.wikipedia.org/wiki/Havel–Hakimi_algorithm

   A simple graph contains no double edges or loops. [1] The degree sequence is a list of numbers in nonincreasing order indicating the number of edges incident to each vertex in the graph. [2] If a simple graph exists for exactly the given degree sequence, the list of integers is called graphic. The Havel-Hakimi algorithm constructs a special ...

5. Dual graph - Wikipedia

   en.wikipedia.org/wiki/Dual_graph

   The simple planar graphs whose duals are simple are exactly the 3-edge-connected simple planar graphs. [10] This class of graphs includes, but is not the same as, the class of 3-vertex-connected simple planar graphs. For instance, the figure showing a self-dual graph is 3-edge-connected (and therefore its dual is simple) but is not 3-vertex ...

6. Spacetime diagram - Wikipedia

   en.wikipedia.org/wiki/Spacetime_diagram

   At its most basic level, a spacetime diagram is merely a time vs position graph, with the directions of the axes in a usual p-t graph exchanged; that is, the vertical axis refers to temporal and the horizontal axis to spatial coordinate values.

7. Erdős–Rényi model - Wikipedia

   en.wikipedia.org/wiki/Erdős–Rényi_model

   A graph generated by the binomial model of Erdős and Rényi (p = 0.01) In the (,) model, a graph is chosen uniformly at random from the collection of all graphs which have nodes and edges. The nodes are considered to be labeled, meaning that graphs obtained from each other by permuting the vertices are considered to be distinct.
