Alfred W. Hales
Alfred Washington Hales (born November 30, 1938) is an American mathematician, a professor emeritus of mathematics at the University of California, Los Angeles, and one of the namesakes of the Hales–Jewett theorem. He was born in Pasadena, California.
As an undergraduate, Hales was a two-time Putnam Fellow for the California Institute of Technology, in 1958 and 1959. Hales stayed at Caltech for his graduate studies, earning his Ph.D. in 1962 under the supervision of Robert P. Dilworth. He is the former chair of the mathematics department at UCLA, and in 2010 became chair of the board of trustees of the Institute for Pure and Applied Mathematics at UCLA.
The Hales–Jewett theorem was published by Hales and Jewett in 1963. Now a standard part of Ramsey theory, Hales and Jewett motivated their theorem as a form of game theory: it shows that certain high-dimensional generalizations of tic tac toe cannot have any tied positions.
Awards and honors
In 1971, Hales shared the George Pólya Prize with Ronald Graham, Klaus Leeb, Bruce Lee Rothschild, and R. I. Jewett, for their work in Ramsey theory. In 2009, Hales was elected a Fellow of the AAAS, and in 2012 he became a fellow of the American Mathematical Society.
