Robin Hartshorne

Robert Cope " Robin " Hartshorne ( born March 15, 1938 in Boston) is an American mathematician who is engaged in algebraic geometry.

Hartshorne was 1958 Putnam Fellow, graduated from Harvard University with David Mumford and Oscar Zariski and in Paris with Jean -Pierre Serre and Alexander Grothendieck and in 1963 received his doctorate from Princeton University with a dissertation Connectedness of the Hilbert Scheme at John Coleman Moore and Zariski. After that, he was a Junior Fellow at Harvard, where Grothendieck gave lectures and seminars regularly. He was a professor at Harvard, and in 1972 professor at the University of California, Berkeley. He was a guest professor at the College de France in Paris and Kyoto, where he delivered his lectures in Japanese.

In 1997, he broke Zeuthen's problem, which had asked the Royal Danish Academy of Sciences in 1901 as price task (each irreducible family of singularity free space curves border curves which are composed of straight lines? ) In a negative sense.

His textbook on algebraic geometry is a standard work. It uses Grothendieck's language of schemes. It also deals with elliptic curves and algebraic surfaces and even the Weil conjectures. In 1979 he received the Leroy P. Steele Prize.

Hartshorne is married ( with a psychotherapist ) and has two children. He plays the flute and is an experienced mountaineer.
