PhD in Mathematics from the University of Valencia (Spain). He furthered his academic career at the Department of Mathematical Analysis in the same institution, where he is currently a professor. His research focuses on nonlinear partial differential equations.
The aim of this article is to highlight some previous challenges that were also a stimulus to finding proof for some interesting results. With this pretext, we present three moments in the history of mathematics that were important for the development of new lines of research.
The Clay Mathematics Institute made a list of seven problems in May 2000; they were called the «millennium problems». Finding their solution has an added incentive: each solver will receive a million dollars as a prize.
