Complete bipartite graphs flexible in the plane

open access: yesSbornik: Mathematics, 2023
A complete bipartite graph $K_{3,3}$, considered as a planar linkage with joints at the vertices and with rods as edges, is in general inflexible, that is, it admits only motions as a whole. Two types of its paradoxical mobility were found by Dixon in 1899. Later on, in a series of papers by several different authors the question of the flexibility of $

Matching transformation graphs of cubic bipartite plane graphs

open access: yesDiscrete Mathematics, 2003
If \(M\) is any perfect matching of a connected cubic bipartite plane graph \(G\), then the authors prove that \(G\) has at least two disjoint \(M\)-alternating faces. This result is best possible in the sense that there are such graphs which do not have three disjoint \(M\)-alternating faces for some perfect matching \(M\).

1-factors and characterization of reducible faces of plane elementary bipartite graphs

open access: yesDiscussiones Mathematicae Graph Theory, 2012
As a general case of molecular graphs of benzenoid hydrocarbons, we study plane bipartite graphs with Kekule structures (1-factors). A bipartite graph G is called elementary if G is connected and every edge belongs to a 1-factor of G. Some properties of the minimal and the maximal 1-factor of a plane elementary graph are given. A peripheral face f of a

Plane subgraphs in geometric complement of 2-factor and complete bipartite geometric graph

open access: yesElectronic Notes in Discrete Mathematics, 2006
Abstract In this article we study when there exist non-crossing subgraphs in a geometric complement of 2-factor and in a complete bipartite geometric graph.

A Sufficient Condition for Cubic 3‐Connected Plane Bipartite Graphs to be Hamiltonian

open access: yesJournal of Graph Theory
ABSTRACTBarnette's conjecture asserts that every cubic 3‐connected plane bipartite graph is hamiltonian. Although, in general, the problem is still open, some partial results are known. In particular, let us call a face of a plane graph big (small) if it has at least six edges (it has four edges, respectively). Goodey proved for a 3‐connected bipartite
