Willard Milnor and his mother was Emily Cox Milnor. He continued on to graduate school at Princeton under the direction of Ralph Fox and submitted his dissertation, entitled " Isotopy of Links ", which concerned link groups a generalization of the classical knot group and their associated link structure, in Upon completing his doctorate he went on to work at Princeton.

He was a professor at the Institute for Advanced Study from to Research[ edit ] One of his published works is his proof in of the existence of 7-dimensional spheres with nonstandard differential structure. Later, with Michel Kervaire , he showed that the 7-sphere has 15 differentiable structures 28 if one considers orientation. An n-sphere with nonstandard differential structure is called an exotic sphere , a term coined by Milnor.

He gave a complete inventory of differentiable structures in spheres of all dimensions with Kervaire, and only continued till Egbert Brieskorn found simple algebraic equations for 28 complex hypersurfaces in complex 5-space such that their intersection with a small sphere of dimension 9 around a singular point is diffeomorphic to these exotic spheres.

In Milnor disproved the Hauptvermutung by illustrating two simplicial complexes that are homeomorphic but combinatorially distinct. He introduced the growth invariant in a finitely presented group and the theorem stating that the fundamental group of a negatively curved Riemannian manifold has exponential growth became a striking point in the foundation for modern geometric group theory , and the basis for the theory of a hyperbolic group in by Mikhail Gromov.

In Milnor introduced a definition of attractor. Milnor cast his eye on dynamical systems theory in the mids. By that time the Smale program in dynamics had been completed. The first choice, one-dimensional dynamics, became the subject of his joint paper with Thurston.

Even the case of a unimodal map, that is, one with a single critical point, turns out to be extremely rich. He was an editor of the Annals of Mathematics for a number of years after He has written a number of books.

Awards and honors[ edit ] In Milnor was awarded the Fields Medal for his work in differential topology.
