The many diverse articles presented in these three volumes, collected on the occasion of Alexander Grothendieck's sixtieth birthday and originally published in 1990, were offered as a tribute to one of the world's greatest living mathematicians. Grothendieck changed the very way we think about many branches of mathematics. Many of his ideas, revolutionary when introduced, now seem so natural as to have been inevitable. Indeed, it is difficult to fully grasp the influence his vast contributions to modern mathematics have subsequently had on new generations of mathematicians. Many of the groundbreaking contributions in these volumes contain material that is now considered foundational to the subject. Topics addressed by these top-notch contributors match the breadth of Grothendieck's own interests, including: functional analysis, algebraic geometry, algebraic topology, number theory, representation theory, K-theory, category theory, and homological algebra.

ltats - avec une generalite minimale, souvent insuffisante pour les applications -et une idee de leur demonstration. Pour des resultats complets, ou des demonstrationsdetaillees, SGA 4 reste indispensable.Le "Rapport sur la formule des traces" contient une demonstration complete dela formule des traces pour l'endomorphisme de Frobenius. La demonstration est celledonnee par Grothendieck dans SGA 5, elaguee de tout detail inutile. Ce rapportdevrait permettre a utilisateur d'oublier SGA 5, qu'on pourra considerer comme uneserie de digression, certaines tres interessantes. Son existence permettra de publierprochainement SGA 5 tel quel. Il est complete par l'expose "Applications de laformule des traces aux sommes trigonometriques" qui explique comment la formuledes traces permet l'etude de sommes trigonometriques, et donne des exemples..

Alexander Grothendieck's concepts turned out to be astoundingly powerful and productive, truly revolutionizing algebraic geometry. He sketched his new theories in talks given at the Seminaire Bourbaki between 1957 and 1962. He then collected these lectures in a series of articles in Fondements de la geometrie algebrique (commonly known as FGA).
