On the Galois map for groupoid actions
Antonio Paques, Thaísa Tamusiunas
Some conditions for the Galois map to be injective are given in the groupoid acting on a noncommutative ring context. In the particular case in which the Galois extension is a cent…
Restriction and Extension of Partial Actions
Dirceu Bagio, Antonio Paques, Héctor Pinedo
Given a partial action of a connected groupoid on a ring and an object of , the isotropy group …
Partial generalized crossed products and a seven-term exact sequence
M. Dokuchaev, A. Paques, H. Pinedo +1
For a partial Galois extension of commutative rings we give a seven term exact sequence which generalize the Chase-Harrison-Rosenberg sequence.
On partial skew groupoids rings
Dirceu Bagio, Antonio Paques, Héctor Pinedo
Given a partial action of a connected groupoid on an associative ring we investigate under what conditions the partial skew groupoid ring $A\star_α\mathcal{G}…
Lifting partial actions: from groups to groupoids
Dirceu Bagio, Antonio Paques, Héctor Pinedo
In this paper, we are interested in the study of the existence of connections between partial groupoid actions and partial group actions. Precisely, we prove that there exists a da…
Partial Galois cohomology and related homomorphisms (expanded version)
M. Dokuchaev, A. Paques, H. Pinedo
For a partial Galois extension of commutative rings we give a seven terms sequence, which is an analogue of the Chase-Harrison-Rosenberg sequence.
