An interview with Jean-Pierre Serre - mklabgr - 09-15-2026
The article is an extensive 2026 interview with Jean-Pierre Serre, one of the most influential mathematicians of the 20th and 21st centuries, conducted by Javier Fresán shortly before Serre’s 100th birthday. Serre reflects on how he discovered mathematics as a teenager, his early involvement with Bourbaki, and the mathematicians who shaped him, including Henri Cartan, André Weil, Claude Chevalley, and Alexander Grothendieck.
He discusses his fascination with algebra, number theory, algebraic groups, Galois representations, and modular forms, while offering candid assessments of his contemporaries. A recurring theme is his preference for concrete, elegant mathematics and his belief that mathematics should be approached with curiosity rather than excessive specialization.
The interview also provides fascinating accounts of Serre's major mathematical discoveries. He describes his work on homotopy groups of spheres, including the insight that emerged during a train journey and led to his thesis, as well as later work on finite groups, representations, modular forms, and Galois representations. Serre emphasizes that his mind "likes to play" rather than concentrate on a single famous problem, explaining why he never seriously pursued the Riemann hypothesis.
He also discusses mistakes and periods of difficulty, showing a remarkably experimental attitude toward research: formulate a plausible idea, calculate, test it, and move on when necessary. Overall, the interview portrays Serre not simply as a monumental mathematician, but as a remarkably curious, independent, and playful thinker whose work has connected topology, algebra, geometry, and number theory.
