**Interpolation and model theoretic forcing – some new perspectives.**

(A lecture in **Cantor Meets Robinson – Set theory, model theory and their philosophy. **University of Campinas, Brazil, December 2018.)

Model Theoretic Forcing has been interweaved with interpolation theorems in infinitary logic since the early work of Mostowski, Vaught, Harnik and others. I will present some of these historical connections and their effect on Shelah’s much more recent logic . In particular I will focus on some connections between model theoretic forcing and the model theory of abstract elementary classes.
