Professor of physics at the Institute for Advanced Study, Princeton, USA.
Witten has almost single-handedly constructed a new branch of mathematical physics. He has remained the leading exponent of string theory and related efforts to unify the four fundamental forces of nature into one mathematical picture.
Witten became well-known for his discovery of new instanton solutions to the Yang-Mills equations and for relating super-symmetric quantum mechanics to Morse theory and index theory. Other highlights of Witten's work include his proof of the positivity of energy in classical relativity, his interpretation of unusual symmetries in physics, including mirror symmetry and SL(2,Z) invariance, his proposals leading to the discovery of new rigidity theorems, and his picture of invariants in low dimensional topology and geometry, including the discovery of the Seiberg-Witten equations and their relation to geometry.
