In this paper we characterize the minimal left ideals of a Leavitt path algebra as those ones which are isomorphic to principal left ideals generated by line point vertices, that is, by vertices… (More)

In this paper, results known about the artinian and noetherian conditions for the Leavitt path algebras of graphs with finitely many vertices are extended to all row-finite graphs. In our first main… (More)

The main aim of the paper is to give a socle theory for Leavitt path algebras of arbitrary graphs. We use both the desingularization process and combinatorial methods to study Morita invariant… (More)

OBJECTIVE
To examine risk factors for preinvasive and invasive lesions of the cervix in Venezuelan female sex workers (FSW).
METHODS
A total of 438 FSW were analysed. Each FSW had their clinical… (More)

In this paper we introduce the concept of purely infinite rings, which in the simple case agrees with the already existing notion of pure infiniteness. We establish various permanence properties of… (More)

OBJECTIVE
To determine the prevalence of preinvasive and invasive lesions of the cervix in sexual workers.
MATERIALS AND METHODS
A total of 438 prostitutes were analyzed. Each prostitute had a… (More)

In this paper a bijection between the set of prime ideals of a Leavitt path algebra LK(E) and a certain set which involves maximal tails in E and the prime spectrum of K[x,x−1] is established.… (More)
