A stroll through hyperbolic geometry : a dialogue between Nalini Anantharaman and William Marx

How do you move on a hyperbolic surface? What's the unexpected link between the metro network and a mountain landscape? Mathematician Nalini Anantharaman, holder of the Spectral Geometry chair at the Collège de France, answers questions from critic and historian William Marx, holder of the Comparative Literatures chair. As serious as it is light-hearted, this interview, in connection with Nalini Anantharaman's lecture in 2024-2025, invites us with as much rigor as pleasure to glimpse the imaginary of her field of research.
