Italian mathematician (1940–2024)
Enrico Giusti (28 October 1940 – 26 March 2024) was an Italian mathematician mainly known for his contributions to the fields of calculus of variations, regularity theory of partial differential equations, minimal surfaces and history of mathematics. He was professor of mathematics at the Università di Firenze; he also taught and conducted research at the Australian National University at Canberra, at the Stanford University and at the University of California, Berkeley. After retirement, he devoted himself to the managing of the "Giardino di Archimede", a museum entirely dedicated to mathematics and its applications. Giusti was also the editor-in-chief of the international journal dedicated to the history of mathematics "Bollettino di storia delle scienze matematiche" ("Bulletin of the history of the mathematical sciences").
One of Giusti's most famous results, obtained with Enrico Bombieri and Ennio De Giorgi, concerned the minimality of Simons' cones, and made it possible to disprove the validity of Bernstein's theorem in dimensions larger than 8. The work on minimal surfaces was mentioned in the citation of the Fields Medal eventually awarded to Bombieri in 1974.
Giusti had a sustained interest in the history of mathematics, e.g. the mathematics of Pierre de Fermat (see Giusti 2009). At the time of his death, he was the director of the Garden of Archimedes, a museum devoted to mathematics in Florence, Italy.
Giusti died in Florence on 26 March 2024, at the age of 83.
Awards.
Giusti won the Caccioppoli Prize of the Italian Mathematical Union in 1978 and in 2003 was awarded the national medal for mathematics by the Accademia Nazionale delle Scienze (dei XL).
