Abstract The partial group algebra of a group G over a field K , denoted by K par ( G ), is the algebra whose representations correspond to the partial representations of G over K -vector spaces. In this paper we study the structure of the partial group algebra K par ( G ), where G is a finite group. In particular, given two finite abelian groups G 1 and G 2 , we prove that if the characteristic of K does not divide the order of G 1 , then K par ( G 1 ) is isomorphic to K par ( G 2 ) if and… 
Isomorphisms of Partial Group Rings
We prove that if two finite groups G1 and G2 admit an isomorphism between their lattices of subgroups which preserves subgroup rings over a commutative ring K then the partial group rings Kpar G1 and
Partial and global representations of finite groups
Given a subgroup H of a finite group G, we begin a systematic study of the partial representations of G that restrict to global representations of H. After adapting several results from [DEP00]
On Strongly Associative Group Algebras
Given a partial action α of a group G on the group algebra FH, where H is a finite group and F is a field whose characteristic p divides the order of H, we investigate the associativity question of

Associativity of crossed products by partial actions, enveloping actions and partial representations
Given a partial action a of a group G on an associative algebra A, we consider the crossed product A × α G. Using the algebras of multipliers, we generalize a result of Exel (1997) on the
On finite degree partial representations of group
We establish a one-to-one correspondence between the irreducible finite degree partial rep tions of a groupG and the (usual) irreducible representations of certain ideals of a groupoid a constructed
Dilations of partial representations of Hopf algebras
The notion of a dilation for a partial representation of a Hopf algebra, which in case the partial representation origins from a partial action coincides with the enveloping action, is introduced to study the interactions between partial and global representation theory.
On elementary domains of partial projective representations of groups
We characterize the finite groups containing only elementary domains of factor sets of partial projective representations. A condition for a finite subset A of a group G, which contains the unity of

Partial Representations and Amenable Fell Bundles over Free Groups
We show that a Fell bundle B = {B_t}_{t \in F}, over an arbitrary free group F, is amenable, whenever it is orthogonal (in the sense that B_x^* B_y = 0, if x and y are distinct generators of F) and
A class ofC*-algebras and topological Markov chains
In this paper we present a class of C*-algebras and point out its close relationship to topological Markov chains, whose theory is part of symbolic dynamics. The C*-algebra construction starts from a
The algebraic structure of group rings
There appeared in 1976 an expository paper by the present author [52] entitled "What is a group ringV This question, rhetorical as it is, may nevertheless be answered directly by saying that for a

Partial actions of discrete groups on C∗-algebras and the associated crossed products have been studied by Exel and McClanahan. We characterise these crossed products in terms of the spectral
Amenability for Fell bundles.
Given a Fell bundle $\B$, over a discrete group $\Gamma$, we construct its reduced cross sectional algebra $C^*_r(\B)$, in analogy with the reduced crossed products defined for C*-dynamical systems.
