Oeuvres mathématiques d'Évariste Galois presents the collected mathematical writings of the French mathematician Évariste Galois, whose revolutionary ideas laid the groundwork for modern group theory and the solvability of polynomial equations. Published posthumously in 1897 by Gauthier-Villars et fils, this volume brings together his seminal memoirs and letters that introduced the concept of a group and demonstrated the criteria for when a polynomial equation can be solved by radicals. Though Galois died at the age of twenty, his insights transformed algebra and influenced subsequent developments in geometry, number theory, and physics. The edition reproduces the original French texts, preserving the notation and style of the nineteenth century while offering readers access to the profound legacy of a genius whose work continues to inspire mathematical research today.
