Gabriel Navarro Ortega


Gabriel Navarro Ortega is a Spanish mathematician specializing in group theory, and representation theory of finite groups. Currently he is a full professor at the Universitat de València.

Career

Navarro received his PhD at the Universitat de València in 1989. He held a Fulbright post doctoral position at MSRI and at the University of Wisconsin-Madison under the supervision of I. M. Isaacs. He is fellow of the American Mathematical Society and Distinguished Speaker of the European Mathematical Society.
In 2024 together with G. Malle, A. Schaeffer-Fry and P. H. Tiep, he completed the proof of Brauer's Height Zero Conjecture. He also extended the McKay Conjecture . Together with I. M. Isaacs and G. Malle, he reduced the McKay conjecture to a question of finite simple groups establishing the path for its final solution by M. Cabanes and B. Späth in 2024. This reduction inspired several other reductions, such as the Alperin Weight Conjecture or the Alperin-McKay conjecture.
