Abstract

Finitary abstract elementary classes is a subclass of AECs which was motivated by some well-behaved syntactical examples of AECs such as excellent sentences in $L_{\omega_1,\omega}$ and homogeneous model theory, which however lack compactness. We present some examples of these frameworks and discuss which properties of the latter ones do or do not generalize to finitary AECs.
