Claudio Baiocchi (August 20, 1940 – December 14, 2020) was an Italian mathematician.
He worked 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.
In 1974 he was an invited speaker at the International Congress of Mathematicians in Vancouver.
