Galois Cohomology

open access: yes, 1997
This volume is an English translation of "Cohomologie Galoisienne" . The original edition (Springer LN5, 1964) was based on the notes, written with the help of Michel Raynaud, of a course I gave at the College de France in 1962-1963.

Cohomological Invariants in Galois Cohomology

open access: yes, 2003
This volume is concerned with algebraic invariants, such as the Stiefel-Whitney classes of quadratic forms (with values in Galois cohomology mod 2) and the trace form of tale algebras (with values in the Witt ring).

GENERALISED IMAGINARIES AND GALOIS COHOMOLOGY

The Journal of Symbolic Logic, 2016
AbstractThe objective of this article is to characterise elimination of finite generalised imaginaries as defined in [9] in terms of group cohomology. As an application, I consider series of Zariski geometries constructed [10, 23, 24] by Hrushovski and Zilber and indicate how their nondefinability in algebraically closed fields is connected to ...
