Stably projectionless Fra\"iss\'e limits

Abstract

We realise the algebra $\mathcal W$, the algebra $\mathcal Z_0$ and the algebras $\mathcal Z_0\otimes A$, where $A$ is a unital UHF algebra as Fra\"iss\'e limits of suitable classes of structures. In doing so, we show that such algebras are generic objects without the use of any classification result.
