During the V CLAM (Congreso Latinoamericano de Matemáticas) at Universidad del Norte in Barranquilla, I gave the lecture Modular Invariants, towards Real Multiplication.
A blackboard lecture for the Oxford Logic seminar on quantum-j. Here, some preparatory notes.
For the CUNY Logic Workshop I gave the lecture The Model Theory of some j-functions, in March of 2016.
During the Helsinki Model Theory Days (University of Helsinki, Mathematics Department) in May 2015 I gave the lecture Model Theory for Modular Invariants.
