Nicolas Bergeron (1975 – 2024)
It was with immense sadness that we learned of the passing of Nicolas Bergeron on Thursday, February 15, 2024. Nicolas had been a Professor at the DMA since 2018. Trained as a geometer, Nicolas combined great culture and curiosity with a profoundly coherent vision of mathematics. His work left its mark on topology, group theory and symmetric spaces, number theory and algebraic geometry. We recall his enthusiasm in recent months, his good humor and modesty as he shared with us the progress of his collaboration with Pierre Charollois and Luis Garcia.
