Daniel Stuart Freed (born 17 April 1959) is an American mathematician, specializing in global analysis and its applications to supersymmetry, string theory, and quantum field theory. He is currently the Shiing-Shen Chern Professor of Mathematics at Harvard University.
Freed studied at Harvard University, where he received his bachelor's and master's degrees in 1981. He received his Ph.D. from the University of California, Berkeley in 1985 with thesis The geometry of loop groups under Isadore Singer. [1] As a postdoc, Freed was a Moore Instructor at the Massachusetts Institute of Technology, and then became an assistant professor at the University of Chicago. Beginning in 1989, he was an associate professor, and from 1994, a professor at the University of Texas at Austin. From 1996 to 1998, he was at the Institute for Advanced Study (IAS) and he was a visiting scientist at the Institut des Hautes Études Scientifiques (1995, 1999). From 1989 to 2022, he was a professor at the University of Texas at Austin.
In the academic year 2002/2003, Freed was a Guggenheim Fellow, [2] and from 1988 to 1992, a Sloan Fellow. In 2002, he was an invited speaker at the International Congress of Mathematicians in Beijing (Twisted K-theory and loop groups). He is one of the founders of the IAS/Park City Mathematics Institute and is, since 2006, a member of the board of trustees of the Mathematical Sciences Research Institute, where he has belonged to the scientific advisory board since 2002. He is a Fellow of the American Mathematical Society.
Edward Witten is an American theoretical physicist known for his contributions to string theory, topological quantum field theory, and various areas of mathematics. He is a professor emeritus in the school of natural sciences at the Institute for Advanced Study in Princeton. Witten is a researcher in string theory, quantum gravity, supersymmetric quantum field theories, and other areas of mathematical physics. Witten's work has also significantly impacted pure mathematics. In 1990, he became the first physicist to be awarded a Fields Medal by the International Mathematical Union, for his mathematical insights in physics, such as his 1981 proof of the positive energy theorem in general relativity, and his interpretation of the Jones invariants of knots as Feynman integrals. He is considered the practical founder of M-theory.
Lars Valerian Ahlfors was a Finnish mathematician, remembered for his work in the field of Riemann surfaces and his textbook on complex analysis.
