biography of the mathematician Jacques Feldbau, and she documented the genesis of the modern holomorphic dynamics, with detailed portraits of the main protagonists: Pierre Fatou, Gaston Julia and Paul Montel. She contributes regularly on historical subjects to the mathematics popularisation website . As a writer Alongside her activity as a mathematician, Audin leads an intense literary activity on her own and, since 2009, within the Oulipo. History of the Paris Commune Passionate about the insurrection of the Paris Commune of 1871, Audin has written five books on this topic to document its history as well as its memory: two novels published by Gallimard, Comme une rivière bleue (2017) and Josée Meunier, 19 rue des Juifs (2021), as well as three historical books published by . The first, Eugène Varlin, bookbinding worker 1839-1871 (2019), is an anthology of the various writings of Eugène Varlin, some of which have not been published since their original release. The second, C'est la nuit surtout que le combat devient furieux (2020), publishes the correspondence between , an unknown paramedic, and her Fourierist family, during the few months of the Parisian insurrection. The last, La Semaine sanglante: Mai 1871. Légendes et comptes (2021), proposes a new counting of the deaths of Bloody Week, going up to “certainly 15,000 dead”. Activity within the Oulipo Audin was guest of honor at a meeting of Oulipo on the initiative of Jacques Roubaud, following the publication of her book Souvenirs sur Sofia Kovalevskaya, which mixes in a discontinuous form anecdotes, precise mathematics, testimonials, excerpts of correspondence with commentary and even literary pastiches. There are references to the Oulipo in testimonial chapters entitled “Je me souviens” in reference to Georges Perec, or even in a pastiche of Cosmicomics by Italo Calvino. She became part of Oulipo in 2009, as the first member to be both a mathematician and a writer. Mathematics is for her both a source of inspiration for the constraints she invents and a recurring theme in her literary work. For example, in her novel La formule de Stokes, the heroine is a mathematical formula. She invented constraints of a geometric nature such as Pascal's or Désargues' constraint. Pascal's constraint was experienced in her online story Mai Quai Conti which evokes the history of the Académie des sciences during the Paris Commune: the relationships between the characters of the story are determined by the position of the points of
