چکیده
|
In this paper, we describe the primitive ideal space of the c^∗ -algebra c^∗ (g) associated to the ultragraph g. we investigate the structure of the closed ideals of the quotient ultragraph c^∗ -algebra c^∗ (g/(h, s)) which contain no nonzero set projections and then we characterize all non gauge-invariant primitive ideals. our results generalize the hong and szymanski’s description of the primitive ideal space of a graph c^∗ -algebra by a simpler method.
