Carlo Pagano awarded André Aisenstadt Prize

Carlo Pagano of Concordia University, currently a visitor at Max Planck Institute for Mathematics in Bonn, has received the 2025 André Aisenstadt Prize. This celebrates the achievements of young Canadians in both pure and applied mathematics. 

In joint work with Peter Koymans, he settled Stevenhagen's conjecture on the negative Pell equation, which is a very strong result in arithmetic statistics. Their breakthrough was covered extensively in the Quanta magazine and can be found here.

But Peter and Carlo have not stopped there. They switched gears and are now tackling problems concerning decidability, in particular related to the (non-)existence of an algorithm that determines, under certain assumptions, whether a Diophantine equation has a solution. You can read more about this in another Quanta magazine article about their work.

Carlo’s strong ties to MPIM include his two year postdoctoral stay, followed by multiple subsequent visits.
