Iacopo Barsotti

Iacopo Barsotti, Jacopo Barsotti, ( born April 28, 1921 in Turin, † October 27, 1987 in Padua ) was an Italian mathematician who dealt with algebraic and arithmetic geometry.

Barsotti received his Laurea degree in 1942 at the Scuola Normale Superiore in Pisa, his military service and then returned to Pisa. 1946 to 1948 he was an assistant of Francesco Severi in Rome. It was founded in 1945 with Oscar Zariski his doctorate at Princeton University, where he studied a long time. He was until 1960 a professor at the University of Pittsburgh and then at Brown University. In 1961, he was following a competition Professor of Geometry in Pisa and from 1968 Professor of Geometry at the University of Padua, where he remained until his death.

He dealt with the theory of algebras and algebraic geometry, and specifically abelian varieties over fields of finite characteristic.

In 1962, he led with abelian varieties in positive characteristic associated Barsotti -Tate groups, named after Alexander Grothendieck (1971 ) searches for John T. Tate (1967, who introduced it as a p- divisible groups). They were of importance in the development of the crystalline cohomology of Grothendieck. He also introduced generalized theta functions.

In 1982 he was at the Institute for Advanced Study.

His graduate student Francesco Baldassarri was his successor at Padua.
