The four-color theorem states that any map in a plane can be colored using four-colors in such a way that regions sharing a common boundary (other than a single point) do not share the same color. This problem is sometimes also called Guthrie's problem after F. Guthrie, who first conjectured the theorem in 1852. The conjecture was then communicated to de Morgan and thence into the general.
THEOREM 1. If T is a minimal counterexample to the Four Color Theorem, then no good configuration appears in T. THEOREM 2. For every internally 6-connected triangulation T, some good configuration appears in T. From the above two theorems it follows that no minimal counterexample exists, and so the 4CT is true. The first proof needs a computer.
The 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. The four color theorem is particularly notable for being the first major theorem proved by a computer. Interestingly, despite the problem being motivated by mapmaking, the theorem is not.
The Four Color Theorem and Kuratowski's Theorem are two fundamental results in discrete mathematics, specifically in the field of graph theory. Both theorems address the properties of planar graphs but from different perspectives. In this article, we will understand about Four Color Theorem and Kuratowski's Theorem in Discrete Mathematics, their definition, examples, and semantic differences.
