: he exhibited a maximal clone
Clone (algebra)
In universal algebra, a clone is a set C of operations on a set A such that*C contains all the projections , defined by ,*C is closed under composition : if f, g1, …, gm are members of C such that f is m-ary, and gj is n-ary for every j, then the n-ary operation is in C.Given an algebra...

 of monotone operations which is not finitely generated. He obtained partial results concerning the Hanna Neumann conjecture
Hanna Neumann conjecture
In the mathematical subject of group theory, the Hanna Neumann conjecture is a statement about the rank of the intersection of two finitely generated subgroups of a free group. The conjecture was posed by Hanna Neumann in 1957...

 and Péter Hajnal which was known to imply the Stanley–Wilf conjecture. With topological methods he proved that if is a finite set system consisting of the unions of intervals on two disjoint lines, then holds, where is the least number of points covering all elements of and is the size of the largest disjoint subsystem of . Tardos worked out a method for optimal probabilistic fingerprint codes. Although the mathematical content is hard, the algorithm is easy to implement.
