Abstract:

Let A be a simple separable non-elementary unital stably finite nuclear C*-algebra with strict comparison. One of Kirchberg¡¯s result showed that central sequence algebra of A is non-simple. We show that every two nonzero ideals of the central sequence algebra of A contain a common fast vanishing ideal. As a consequence, we show that the central sequence algebra of A is prime. We also discuss the tracial version of related concepts. This is based on a joint work with I. Farah, F. Perera, H. Thiel, and E. Vilalta.
