John Forbes Nash Jr.: A Beautiful Mind
Real Algebra contribution
U.S.
Nash did groundbreaking work in the area of real algebraic geometry, His work in mathematics includes the Nash embedding theorem, which shows that every abstract Riemannian manifold can be isometrically realized as a submanifold of Euclidean space. He also made significant contributions to the theory of nonlinear parabolic partial differential equations and to singularity theory.
