… In Section 2, we recall for reader’s convenience some facts used in the paper, whereas
the homomorphisms of the sequence are given in Sections 4, 5 and 6. Our proofs are
constructive and the partial case is essentially more laborious than the classical one, so that
in this article we only build up the homomorphisms, and the proof of the exactness of the
sequence will be given in a forthcoming paper. Some of the routine details are omitted,
which can be recovered by the reader or consulted in the arXiv preprint of this article [24] …

… Having at hand partial Galois theory and partial group cohomology we may ask now
what would be the analogue of the Chase-Harrison-Rosenberg exact sequence in the
context of a partial Galois extension of commutative rings. The purpose of the present paper
is to answer this question. The additional new ingredients include a … In Section 2 we
