Robert Brown Gardner

American mathematician

The 1991 publication of Exterior Differential Systems established Robert Brown Gardner as a primary authority on the complex mathematical frameworks developed by Élie Cartan. Born in Tarrytown in 1939, Gardner dedicated his career to refining algorithmic geometric procedures, transforming difficult theoretical concepts into accessible tools for students and practitioners within the field of differential geometry.

Academic Foundation

Gardner began his formal education at Princeton University, graduating in 1959. He pursued a master's degree at Columbia University the following year. His doctoral research concluded in 1965 at the University of California, Berkeley, where he worked under the supervision of the mathematician Shiing-Shen Chern.

Professional Appointments

Following his doctoral studies, Gardner held positions at several institutions, including the Institute for Advanced Study. He served as an assistant professor at Columbia University from 1967 until 1970. In 1971, he joined the faculty at the University of North Carolina at Chapel Hill, where he was appointed a full professor in 1977.

Contributions to Geometry

His primary professional focus involved the popularization and refinement of the methods of Élie Cartan, specifically the Cartan equivalence method. This algorithmic procedure identifies whether two geometric shapes are fundamentally distinct. Throughout his career, he authored or co-authored three books and produced more than fifty academic papers. His mentorship resulted in the guidance of eighteen master's students and thirteen Ph.D. students, including Robert Bryant, who later served as president of the American Mathematical Society.

Selected Publications and Legacy

Gardner co-authored the standard reference text Exterior Differential Systems in 1990 alongside R. Bryant, S. S. Chern, H. Goldschmidt, and P. Griffiths. His other notable works include The Method of Equivalence and Its Applications, Lectures on Exterior Algebras Over Commutative Rings, and Differential Geometric Methods in Partial Differential Equations. Following his death on May 5, 1998, the University of North Carolina Mathematics Department established the Robert Brown Gardner Memorial Fund to support graduate student research.
