The Existential Closedness and Zilber-Pink Conjectures

Abstract

In this paper we survey the history of, and recent developments on, two major conjectures originating in Zilber's model-theoretic work on complex exponentiation -- Existential Closedness and Zilber-Pink. The main focus is on the modular versions of these conjectures and specifically on novel variants incorporating the derivatives of modular functions. The functional analogues of all the conjectures that we consider are theorems which are presented too. The paper also contains some new results and conjectures.
