Robert Thomas Seeley (born February 26, 1932, in Bryn Mawr, Pennsylvania, United States–died November 30, 2016, in Newton, Massachusetts) was a mathematician who worked on pseudo differential operators and the heat equation approach to the Atiyah–Singer index theorem.[1][2]
Seeley did his undergraduate studies at Haverford College, and earned his Ph.D. from the Massachusetts Institute of Technology in 1959, under the supervision of Alberto Pedro Calderón.[3] He taught at Harvey Mudd College and then in 1962 joined the faculty of Brandeis University. In 1972 he moved to the University of Massachusetts Boston; he retired as an emeritus professor.[2] In 2012 he became a fellow of the American Mathematical Society.[4]
