Patrick Dehornoy (born September 11, 1952 in Rouen) is a mathematician at the University of Caen who works on set theory and algebra. He found one of the first applications of large cardinals to algebra by constructing a certain left-invariant total order, called the Dehornoy order, on the braid group.
