  Abstract:
In this paper we compute the projective dimension of the edge ideals of graphs consisting of some cycles and some lines which are joint in a common vertex. Moreover, we show that for such graphs, the arithmetical rank equals the projective dimension. As an application we can compute the arithmetical rank for some homogenous monomial ideals.
