|Title:||Sur Le Groupe Des Extensions Cycliques|
|Abstract:||In this paper we give an explicit and elementary construction of the group of all cyclic extensions of prime degree of a given ring. We give explicit calculations in some particular cases. In the second part, under certains hypotheses concerning the base ring, we give a cohomological interpretation of this group. Next, the crucial question of the existence of primitive element for the algebra extensions of the vase ring is treated and finally, we examine certains cases where primitive elements always exists. © 1980.|
