Partial groupoid actions: globalization, Morita theory, and Galois theory

D Bagio, A Paques - Communications in Algebra, 2012 - Taylor & Francis
In this article, we introduce the notion of a partial action of a groupoid on a ring as well as we
give a criteria for the existence of a globalization of it. We construct a Morita context …

Partial actions: a survey

M Dokuchaev - Contemp. Math, 2011 - books.google.com
In the theory of C∗-algebras a concept of a partial action was introduced as an efficient tool
of their study, permitting to characterize various important classes of C∗-algebras as …

[HTML][HTML] Epsilon-strongly graded rings, separability and semisimplicity

P Nystedt, J Öinert, H Pinedo - Journal of Algebra, 2018 - Elsevier
We introduce the class of epsilon-strongly graded rings and show that it properly contains
both the class of strongly graded rings and the class of unital partial crossed products. We …

Globalization of twisted partial actions

M Dokuchaev, R Exel, J Simón - Transactions of the American …, 2010 - ams.org
Let $\mathcal {A} $ be a unital ring which is a product of possibly infinitely many
indecomposable rings. We establish a criteria for the existence of a globalization for a given …

The twisted partial group algebra and (co) homology of partial crossed products

M Dokuchaev, E Jerez - Bulletin of the Brazilian Mathematical Society …, 2024 - Springer
Given a group G and a partial factor set σ of G, we introduce the twisted partial group
algebra κ par σ G, which governs the partial projective σ-representations of G into algebras …

Partial projective representations and partial actions II

M Dokuchaev, B Novikov - Journal of Pure and Applied Algebra, 2012 - Elsevier
This paper is a continuation of Dokuchaev and Novikov (2010)[8]. The interaction between
partial projective representations and twisted partial actions of groups considered in …

Prime group graded rings with applications to partial crossed products and Leavitt path algebras

D Lännström, P Lundström, J Öinert… - arXiv preprint arXiv …, 2021 - arxiv.org

group graded rings to the class of nearly epsilon-strongly group graded rings which are not …

Twisted partial actions of Hopf algebras

MMS Alves, E Batista, M Dokuchaev… - Israel journal of …, 2013 - Springer
In this work, the notion of a twisted partial Hopf action is introduced as a unified approach for
twisted partial group actions, partial Hopf actions and twisted actions of Hopf algebras. The …

On partial skew groupoid rings

D Bagio, A Paques, H Pinedo - International Journal of Algebra and …, 2021 - World Scientific
Given a partial action α of a connected groupoid 𝒢 on an associative ring A we investigate
under what conditions the partial skew groupoid ring A⋆ α 𝒢 can be realized as a partial …
