Ennio de Giorgi

Ennio de Giorgi (Lecce, February 8, 1928 – Pisa, October 25, 1996) was one of the most influential Italian mathematicians of the 20th century.

He made important contributions to mathematical analysis, in particular to the study of minimal surfaces and to the regularity of the solutions of elliptic partial differential equations.

In terms of the regularity of solutions of elliptic partial differential equations, one of his major contributions was to solve the 19^th Hilbert problem. At roughly the same time he solved it, John Forbes Nash solved it in a completely independent fashion. It is commonly believed that if only one of them had solved it, then that person would have won the prestigious Fields Medal. His work has influenced Luis Caffarelli and many other outstanding mathematicians.
