he developed a method (now known as the Pila-Zannier method) of applying O-minimality In mathematical logic, and more specifically in model theory, an infinite structure (''M'',<,...) which is totally ordered by < is called an o-minimal structure if and only if every to number-theoretical and algebro-geometric problems. Thus they gave a new proof of the Manin–Mumford conjecture
In mathematics, the arithmetic of abelian varieties is the study of the number theory of an abelian variety, or a family of abelian varieties. It goes back to the studies of Pierre de Fermat on what are now recognized as elliptic curves; and has b ...
