Claudio Baiocchi
Claudio Baiocchi (born 1940) is an Italian mathematician. He was a professor at the University of Pavia and since the 1990s he has been a professor of mathematical higher analysis at the Sapienza University.
He works on partial differential equations and the calculus of variations. In 1971 he applied his mathematical methods to a free boundary problem in the filtration of liquids through porous media with applications in civil engineering (by using the Baiocchi transform).[1][2][3]
His later research dealt with, among other topics, the Collatz problem,[4] cellular automata and Turing machines.[5]
In 1970 Baiocchi received the Caccioppoli Prize. In 1974 he was an invited speaker at the International Congress of Mathematicians in Vancouver. He was elected to the Accademia dei XL[6] and the Accademia dei Lincei.
