Guido Stampacchia

Guido Stampacchia ( born March 26, 1922 in Naples, † April 27, 1978 in Paris ) was an Italian mathematician who worked on Analysis.

Life

Stampacchia was the son of an owner of a small iron goods factory, who was forced Mussolini to sell them. He studied from 1940 at the Scuola Normale Superiore in Pisa. In March 1943, he was drafted into the Italian Air Force, made in the summer of 1943 but still his degree and then went into the Italian resistance. In 1944, he won a scholarship to the University of Naples, where he at Renato Caccioppoli ( and Leonida Tonelli, who had taught him in Pisa) received his diploma ( Laurea ). In 1945 he graduated from the final examinations at the Scuola Normale Superiore in Pisa. He was an assistant at the Marine Institute in Naples, where he taught (as well as at the university, where he taught on a voluntary basis ) Analysis. In 1949 he became assistant professor in Naples and in 1951 he received his habilitation ( Liberation docenza ). In 1952, he won a national competition for the professorship at the University of Palermo, but was in the same year at the University of Genoa, where in 1955 he received a full professorship. In 1966 he was awarded an Antonio Feltrinelli Prize. He became a professor at the University of Rome (La Sapienza ) and in 1970 at the University of Pisa in 1968. He died in Paris of a heart attack. He has been a visiting scientist at the College de France and the Courant Institute of Mathematical Sciences of New York University.

He dealt with the calculus of variations, functional analysis and ordinary and partial differential equations. He is with Gaetano Fichera founder of the theory of variational inequalities. While Fichera 1963 emanated from a problem of elasticity theory ( Signorini problem), the starting point of Stampacchia was the regularity theory of partial differential equations. He generalized the 1964 Lax - Milgram and coined the term variational inequality. Soon after, he gave the theory of Jacques -Louis Lions, a more abstract version (pack of Lions and Stampacchia )

In 1967 he became president of the Unione Matematica Italiana. In 1970 he was invited speaker at the International Congress of Mathematicians in Nice ( variational inequalities ) and in Stockholm in 1962 (second order elliptic equations and boundary value problems ).

He was married since 1948 with Sara Naldini, with whom he had four children.

In his honor, the Stampacchia Medal is named.
