Maximal planar graph refers to the planar graph with the most edges, which means no more edges can be added so that the resulting graph is still planar. The Four-Color Conjecture says that every planar graph without loops is 4-colorable. Indeed, in order to prove Four-Color Conjecture, it clearly suffices to show that all maximal planar graphs are 4-colorable. Since this conjecture was proposed in 1852, no mathematical proofs have been invented up until now. Maybe the main reasons lie in the…

### Hamiltonian cycles in planar triangulations with no separating triangles

It is shown that the conclusion of Whitney's theorem still holds if the chords satisfy a certain sparse-ness condition and that a Hamiltonian cycle through a graph satisfying this condition can be found in linear time.

A p-vertex maximal planar graph containing exactly four Hamiltonian cycles for every p ≥ 12 vertices is constructed and it is proved that every 4-connected maximalPlanar graph on p vertices contains at least p/(log2 p) Hamiltoniancycles.

### Tow Maximal Planar Graphs with Path Bichromatic Subgraph Only.

In this paper, it is proved that every bichromatic subgraph of every 4_coloring of maximal planar graphs g9D and g12A is a path. We conjecture that there is not any other graph in all of maximal

A one-way infinite Hamiltonian path is constructed in an infinite 4-connected VAP-free maximal planar graph containing one or two vertices of infinite degree. Combining this result and that of R.

### A theorem on paths in planar graphs

We prove a theorem on paths with prescribed ends in a planar graph which extends Tutte's theorem on cycles in planar graphs [9] and implies the conjecture of Plummer [5] asserting that every

This work generalizes Etourneau's result by giving sufficient conditions in terms of the vertex degrees for G to be dp -connected.

### On paths in planar graphs

This paper generalizes a theorem of Thomassen on paths in planar graphs. As a corollary, it is shown that every 4-connected planar graph has a Hamilton path between any two specified vertices x, y
