2. Outerplanar graph - Wikipedia

   en.wikipedia.org/wiki/Outerplanar_graph

   In graph theory, an outerplanar graph is a graph that has a planar drawing for which all vertices belong to the outer face of the drawing. Outerplanar graphs may be characterized (analogously to Wagner's theorem for planar graphs) by the two forbidden minors K 4 and K 2,3, or by their Colin de Verdière graph invariants. They have Hamiltonian ...

   [2] Episode 4 was initially announced to have been delayed "due to production issues" [6] and then subsequently for another two weeks, [7] before the official anime production announced that the entire series would be rebroadcast from the beginning on April 6, 2020, and aired until June 22, 2020.

4. k-outerplanar graph - Wikipedia

   en.wikipedia.org/wiki/K-Outerplanar_graph

   Baker's technique covers a planar graph with a constant number of -outerplanar graphs and uses their low treewidth in order to quickly approximate several hard graph optimization problems. [ 2 ] In connection with the GNRS conjecture on metric embedding of minor-closed graph families, the k {\displaystyle k} -outerplanar graphs are one of the ...

   HOMRA, led by Mikoto Suoh the Third and Red King, attacks a hotel owned by a gang before being confronted by Scepter 4, led by Reisi Munakata the Fourth and Blue King. . Meanwhile, at Ashinaka High School, an entire campus built on an island, Yashiro Isana gathers unwanted lunch items from other students and makes his way to one of the school rooftops in order to eat with his p

7. Complete graph - Wikipedia

   en.wikipedia.org/wiki/Complete_graph

   Geometrically K 3 forms the edge set of a triangle, K 4 a tetrahedron, etc. The Császár polyhedron, a nonconvex polyhedron with the topology of a torus, has the complete graph K 7 as its skeleton. [15] Every neighborly polytope in four or more dimensions also has a complete skeleton. K 1 through K 4 are all planar graphs.

8. Thickness (graph theory) - Wikipedia

   en.wikipedia.org/wiki/Thickness_(graph_theory)

   That is, if there exists a collection of k planar graphs, all having the same set of vertices, such that the union of these planar graphs is G, then the thickness of G is at most k. [1] [2] In other words, the thickness of a graph is the minimum number of planar subgraphs whose union equals to graph G. [3] Thus, a planar graph has thickness one.

9. Complete bipartite graph - Wikipedia

   en.wikipedia.org/wiki/Complete_bipartite_graph

   A complete bipartite graph of K 4,7 showing that Turán's brick factory problem with 4 storage sites (yellow spots) and 7 kilns (blue spots) requires 18 crossings (red dots) For any k, K 1,k is called a star. [2] All complete bipartite graphs which are trees are stars. The graph K 1,3 is called a claw, and is used to define the claw-free graphs ...
