Gabriele Vezzosi is an italian mathematician, born in Florence (Italy). His main interest is Algebraic Geometry.

He has a MS degree in Physics (University of Florence, under the supervision of Alexandre M. Vinogradov) and a PhD in Mathematics (Scuola Normale Superiore, Pisa, under the supervision of Angelo Vistoli). His first papers dealt with differential calculus over commutative algebras, intersection theory, (equivariant) algebraic K-theory, motivic homotopy theory, and existence of vector bundles on singular algebraic surfaces.

Around 2001-2002 he started his collaboration with Bertrand Toën. Together, they created Homotopical Algebraic Geometry (HAG)[1][2] [3], whose more relevant part is Derived Algebraic Geometry (DAG) [4][5] which is by now a powerful and widespread theory [6]. Slightly later, this theory have been reconsidered, and highly expanded by Jacob Lurie.

More recently, Vezzosi together with Tony Pantev, Bertrand Toën and Michel Vaquié defined a derived version of symplectic structures[7] and studied important properties and examples (an important instance being Kai Behrend's symmetric obstruction theories); further together with Damien Calaque these authors introduced and studied a derived version of Poisson and coisotropic structures[8] with applications to deformation quantization [9].

Lately Toën and Vezzosi (partly in collaboration with Anthony Blanc and Marco Robalo) moved to applications of derived and non-commutative geometry to arithmetic geometry, especially to Spencer Bloch's conductor conjecture[10][11].

Vezzosi also defined a derived version of quadratic forms, and in collaboration with Benjamin Hennion and Mauro Porta, proved a very general formal gluing result along non-linear flags[12] with hints of application to a yet conjectural Geometric Langlands Program for varieties of dimension bigger than 1. Together with Benjamin Antieau, Vezzosi proved an HKR theorem for varieties of dimension p in characteristic p[13].

Vezzosi spent his career so far in Pisa, Florence, Bologna and Paris, has had 3 Phd students, so far (Schürg, Porta and Melani), and is currently full professor at the University of Florence (Italy).
