Stable rank of Leavitt path algebras of arbitrary graphs
The stable rank of Leavitt path algebras of row-finite graphs was computed by
Ara and Pardo. In this paper we extend this for an arbitrary directed graph. In
some parts, we proceed our computation as the row-finite case while in some
parts we use the knowledge about row-finite setting by applying the
desingularizing method due to Drinen and Tomforde. In particular, we
characterize purely infinite simple quotients of a Leavitt path algebra
The Topological Centers Of Module Actions
In this paper, we will study the topological centers of dual of Banach
and we extend some propositions from Lau and into
dual of Banach . Let be a Banach . By using
some new conditions, we show that and
. We also have some conclusions in dual
groups
