This booklet is the 1st straight forward creation to Galois cohomology and its purposes. the 1st half is self contained and offers the elemental result of the idea, together with a close development of the Galois cohomology functor, in addition to an exposition of the final conception of Galois descent. the entire thought is inspired and illustrated utilizing the instance of the descent challenge of conjugacy periods of matrices. the second one a part of the ebook offers an perception of ways Galois cohomology might be worthy to resolve a few algebraic difficulties in numerous energetic study themes, similar to inverse Galois conception, rationality questions or crucial measurement of algebraic teams. the writer assumes just a minimum heritage in algebra (Galois conception, tensor items of vectors areas and algebras).
