Clotilde Armand has offered a €1000 reward for a physical copy of Sorin Grindeanu's mathematical book, which she claims does not exist. This dispute has been ongoing since 2017 when Grindeanu presented the book in an interview. Armand aims to donate an authentic copy to a public library for public access. Previous investigations raised doubts about the book's existence, and Grindeanu's claims have been challenged. Despite presenting photos of the book, questions remain regarding its ISBN and authenticity. The controversy resurfaced in 2021 when mathematicians urged Grindeanu to donate copies for public consultation.
