John William Theodore Youngs
John William Theodore Youngs (mostly quoted JWT Youngs, called Ted Youngs; born August 21, 1910 in Bilaspur , India , † July 20, 1970 in Santa Cruz , California ) was an American mathematician .
Youngs was the son of a missionary. He attended Wheaton College and Ohio State University , where he received his doctorate in 1934 and was a student of Tibor Radó . He then taught at Indiana University for 18 years , including eight years on the math faculty. From 1964 he was a professor at the University of California, Santa Cruz , where he built up the mathematics faculty and was the head of the university's academic senate.
Youngs worked in geometric topology , for example questions of the Frechet equivalence of topological mappings in the area definition. He is known for the theorem of Ringel-Youngs (also: Heawood assumption), the counterpart of the four-color theorem for surfaces of the higher sex, which he proved in 1968 together with Gerhard Ringel . John Youngs was a consultant at Sandia National Laboratories , Rand Corporation, and the Institute for Defense Analyzes, and was a trustee of the Carver Research Foundation Institute in Tuskegee . He was a Guggenheim Fellow . At the University of Santa Cruz, a student math award is named after him.
