Frederick William Galvin is a mathematician, currently a professor at the University of Kansas. His research interests include set theory and combinatorics. His notable combinatorial work includes the proof of the Dinitz conjecture. In set theory, he proved with Andras Hajnal that if is a strong limit cardinal, then holds. The research on extending this result led Saharon Shelah to the invention of PCF theory. Galvin and Shelah also proved the square bracket partition relations and . Galvin... full article at wikipedia
