Valentino Tosatti (born c. 1981) is an Italian mathematician.

## Biography

[edit]

Born c. 1981, in Trieste, Tosatti studied from 2000 at the Scuola Normale Superiore di Pisa and at the University of Pisa, graduating with a laurea in 2004. He then studied at Harvard University, where he graduated with an M.A. in 2005 and a Ph.D. in 2009.[1] His Ph.D. thesis Geometry of complex Monge-Ampère equations was supervised by Shing-Tung Yau.[2][3] Tosatti was from 2009 to 2012 a Joseph Fels Ritt Assistant Professor at Columbia University. At Northwestern University, he was an associate professor from 2012 to 2015 and a full professor from 2015 to 2020. From 2020 to 2022, he taught as a professor at McGill University. In 2022 he became a professor at NYU's Courant Institute of Mathematical Sciences.[1]

Tosatti does research on complex and differential geometry; geometric analysis on complex, Hermitian, and symplectic manifolds; and partial differential equations. He is also interested in the connections of his main research topics with algebraic geometry and dynamical systems.[1]

In 2017, with Gábor Székelyhidi and Ben Weinkove, Valentino Tosatti proved a conjecture published in 1984 by Paul Gauduchon.[4][5] Acta Mathematica published their proof that on n-dimensional compact complex manifolds there is always a Gauduchon metric with prescribed volume form. For this purpose, the behavior of a large class of elliptic nonlinear partial differential equations of second order on Hermitian manifolds had to be investigated.[4]

In 2011, Tosatti received a Blavatnik Award.[6] In 2012, he was awarded a two-year Sloan Research Fellowship.[1] In 2018, he received the Caccioppoli Prize. In 2019, he was elected a Fellow of the American Mathematical Society for "contributions in geometric analysis and complex geometry".[7]
