John A. Thorpe

from Wikipedia, the free encyclopedia

John Alden Thorpe (born February 29, 1936 in Lewiston , Maine ) is an American mathematician who studies differential geometry.

Thorpe studied at the Massachusetts Institute of Technology with a bachelor's degree in 1958 and at Columbia University with a master's degree in 1959 and his doctorate in 1963 with James Eells ( Higher Order Sectional Curvature ). From 1963 to 1965 he was Moore Instructor at MIT and from 1965 Assistant Professor at Haverford College . In 1967/68 he was at the Institute for Advanced Study . From 1968 he was Associate Professor and then Professor at the State University of New York at Stony Brook (SUNY). From 1987 he was professor and dean at the State University of New York in Buffalo and from 1993 at Queens College of the City University of New York , where he was also Provost .

He and Nigel Hitchin created an inequality between topological invariants named after them, which provides a necessary condition for the existence of Einstein metrics on four-dimensional smooth compact manifolds.

From 1984 to 1987 he served on the Board of Governors of the Mathematical Association of America.

From 1998 to 2001 he was Executive Director of the National Council of Teachers of Mathematics.
