**William Hugh Woodin** (born April 23, 1955) is an American mathematician and set theorist at Harvard University. He has made many notable contributions to the theory of inner models and determinacy. A type of large cardinal, the Woodin cardinal, bears his name.

## Biography

Born in Tucson, Arizona, Woodin earned his Ph.D. from the University of California, Berkeley in 1984 under Robert M. Solovay. His dissertation title was *Discontinuous Homomorphisms of C*(*Omega*) *and Set Theory*. He served as chair of the Berkeley mathematics department for the 2002–2003 academic year. Woodin is a managing editor of the Journal of Mathematical Logic. He was elected a Fellow of the American Academy of Arts and Sciences in 2000.^{[1]}

He is the great-grandson of William Hartman Woodin, former Secretary of the Treasury.

## Work

He has done work on the theory of generic multiverses and related concept of Ω-logic which suggested an argument that the continuum hypothesis is either undecidable or false in the sense of mathematical platonism. Woodin criticizes this view arguing that it leads to a counterintuitive reduction in which all truths in the set theoretical universe can be decided from a small part of it. He claims that these and related mathematical results lead (intuitively) to the conclusion that Continuum Hypothesis has a truth value and the Platonistic approach is reasonable.

Woodin now predicts that there should be a way of constructing an inner model for almost all known large cardinals which he calls the Ultimate L and which would have similar properties as Gödel's constructible universe. In particular, the Continuum Hypothesis would be true in this universe.^{[2]}
