## Abstract

I'll discuss the two topological twists of 3d N=4 theories, and explain how to understand them in the AKSZ/BV formalism, and how they relate to twists of 4d N =2 theories. Symplectic duality then takes the form of an equivalence between 3d N=4 theories which interchanges the two topological twists. I'll also introduce monopole operators and explain the role they play in symplectic duality.
