Map color theorem
In mathematics, the four color theorem, or the four color map theorem, states that no more than four colors are required to color the regions of any map so that no two adjacent regions have the same color. Adjacent means that two regions share a common boundary curve segment, not merely a corner … Pogledajte više In graph-theoretic terms, the theorem states that for loopless planar graph $${\displaystyle G}$$, its chromatic number is $${\displaystyle \chi (G)\leq 4}$$. The intuitive statement of the four color theorem – … Pogledajte više The following discussion is a summary based on the introduction to Every Planar Map is Four Colorable (Appel & Haken 1989). Although flawed, Kempe's original purported proof of the four color theorem provided some of the basic tools later used to prove … Pogledajte više While every planar map can be colored with four colors, it is NP-complete in complexity to decide whether an arbitrary planar map can be colored with just three colors. A cubic map can be colored with only three colors if … Pogledajte više Dror Bar-Natan gave a statement concerning Lie algebras and Vassiliev invariants which is equivalent to the four color theorem. Pogledajte više Early proof attempts As far as is known, the conjecture was first proposed on October 23, 1852, when Francis Guthrie, … Pogledajte više The four color theorem has been notorious for attracting a large number of false proofs and disproofs in its long history. At first, The New York Times refused, as a matter of … Pogledajte više Infinite graphs The four color theorem applies not only to finite planar graphs, but also to infinite graphs that can be drawn without crossings in the plane, … Pogledajte više WebThe four color theorem states that any map--a division of the plane into any number of regions--can be colored using no more than four colors in such a way that no two adjacent regions share the same color. A map …

This problem was first posed in the nineteenth century, and it was quickly conjectured that in all cases four colors suffice. This was finally proved in 1976 (see Figure ) with the aid of a computer.

WebThe “four-color” theorem seems to be generalizable as follows. The four-letter alphabet is sufficient to encode unambiguously any set of well-orderings including a geographical map or the “map” of any logic and thus that of all logics or the DNA (RNA) plan(s) of any (all) alive being(s). Then the corresponding maximally generalizing conjecture would state: … Web24. mar 2024. · When the four-color theorem was proved in 1976, the Klein bottle was left as the only exception, in that the Heawood formula gives seven, but the correct bound is six (as demonstrated by the Franklin graph ). The four most difficult cases to prove in the Heawood conjecture were , 83, 158, and 257. See also
