Harry Pollard (mathematician)
Harry Strange Pollard (born February 28, 1919 in Boston , † November 20, 1985 ) was an American mathematician who studied analysis and celestial mechanics .
life and work
Pollard received his doctorate in 1942 from Harvard University under David Widder ( Studies of the Stieltjes Transform ). He was a professor at Cornell University and from 1961 at Purdue University .
In 1952/53 he was at the Institute for Advanced Study .
He dealt in particular with the N-body problem (collisions, asymptotics, virial theorem) in celestial mechanics.
In probability theory, Erdős , Feller and Pollard's theorem is named after him, which is important in renewal theory.
His PhD students include Louis De Branges and Donald Saari .
