Abstract
The main purpose of this paper is to provide explicit computations of the fundamental groups of several algebras. For this purpose, given a -algebra , we consider the category of all connected gradings of by a group and we study the relation between gradings and Galois coverings. This theoretical tool gives information about the fundamental group of , which allows its computation using complete lists of gradings.
