%0 Journal Article %T On separable algebras in Grothendieck Galois theory %A Federico G. Lastaria %J Le Matematiche %D 1996 %I University of Catania %X We give an explicit proof of the fundamental theorem of Grothendieck Galois theory: the category of separable algebras over a field K is anti-equivalent to the category of continuous actions on finite sets of the profinite fundamental group of K. %U http://www.dmi.unict.it/ojs/index.php/lematematiche/article/view/464
