We define the partial group cohomology as the right derived functor of the functor of partial invariants, we relate this cohomology with partial derivations and with the partial augmentation ideal and we show that there ...

Based on the articles Associativity of crossed produts by partial actions, enveloping actions and partial representations" of M. Dokuchaev and R. Exel ([7] and Enveloping Actions for Partial Hopf Actions" of M.M.S. Alves ...

Let 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 twisted partial action of a group on A. If the globalization ...

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 Dokuchaev and Novikov (2010) [8] is treated ...

For a twisted partial action e of a group G on an (associative non-necessarily unital) algebra A over a commutative unital ring k, the crossed product A x(Theta) G is proved to be associative. Given a G-graded k-algebra B ...

The concept of a partial projective representation of a group is introduced and studied. The interaction with partial actions is explored. It is shown that the factor sets of partial projective representations over a field ...

The use of mechanical shear connectors, mainly headed stud bolts, is the most common way to achieve steel-concrete composite action. The encasement of the steel beam in the depth slab results in increase of strength and ...

Estudamos a interação entre álgebras de Steinberg e skew álgebras de grupos parciais e caracterizamos isomorfismos de skew álgebras de grupos que preservam diagonal, sobre álgebras comutativas, em termos de equivalência ...
