Four Colors Suffice: How the Map Problem Was Solved.ROBIN WILSON Robin Wilson is the name of:
In 1852, in a letter to a colleague, Augustus De Morgan Augustus De Morgan (June 27, 1806 – March 18, 1871) was an Indian-born British mathematician and logician. He formulated De Morgan's laws and was the first to introduce the term, and make rigorous the idea of mathematical induction. of London unwittingly presented a mathematical conundrum that perplexed professional and recreational mathematicians for 125 years. Today, some are still not satisfied with the solution. The four-color problem poses this hypothesis: Every map can be colored with at most four colors in such a way that all neighboring countries are colored differently. Wilson charts the history of this problem and details its proof, as posited by Wolfgang Haken Wolfgang Haken (born June 21, 1928) is a mathematician who specializes in topology, in particular 3-manifolds. In 1976 together with colleague Kenneth Appel at the University of Illinois at Urbana-Champaign, Haken solved one of the most famous problems in mathematics, the and Kenneth Appel in 1976. Before this team's success, the efforts of many people, including the author of Alice's Adventures in Wonderland “Alice in Wonderland” redirects here. For other uses, see Alice in Wonderland (disambiguation). Alice's Adventures in Wonderland is a work of children's literature by the English mathematician and author, the Reverend Charles Lutwidge Dodgson, written , known as Lewis Carroll, elucidated the problem and contributed to the mathematics of computing and graph theory. Originally published in the United Kingdom in 2002. Princeton U Pr, 2003, 262 p., b&w photos/illus., hardcover, $24.95. |
