John William Theodore Youngs

John William Theodore Youngs (usually cited JWT Youngs, called Ted Youngs, born August 21, 1910 in Bilaspur, India, † July 20, 1970 in Santa Cruz, California ) was an American mathematician.

Young was the son of a missionary. He attended Wheaton College and Ohio State University, where he received his doctorate in 1934 and a student of Tibor Rado was. He then taught 18 years at Indiana University, which he eight years headed the mathematics department. From 1964 he was professor at the University of California, Santa Cruz, where he was the math faculty built and Chairman of the Academic Senate of the University.

Youngs worked in geometric topology, for example, questions of Frechet equivalence of topological maps in the surface definition. He is best known for the set of Ringel- Youngs (also: Heawood conjecture ), the equivalent of the four- color theorem for surfaces of higher genus, which he proved with Gerhard Ringel 1968. John Young was a consultant at Sandia National Laboratories, the Rand Corporation and the Institute for Defense Analyses and a Trustee of the Carver Research Foundation at Tuskegee Institute. He was Guggenheim Fellow. At the University of Santa Cruz a mathematics prize for students is named after him.
