Thank you very much, Anton. So, first of all, it's a great honor to be invited to this conference. Of course, Maxime has had a huge influence on everything I know. I think I understand. Since I started thinking about mathematics, in my first year of graduate school, my advisor told me that I should read all of Maxime's papers. This was not easy, it took me several years, but somehow this is how I learned everything about topological algebra, operas, the BD formalism, and twistor string theory. I also discovered symmetry in infinity algebra and modular life curves. I remember reading a great paper from 1994 during the European Congress of Mathematics. I spent an incredible amount of time reading this paper, it was great. Today, I want to talk about something that has long been a dream of mine, which is understanding some piece of string theory in mathematics. One of the string theories I would like to consider is superstring theory, which is defined in ten dimensions. One important concept in superstring theory is the AdS/CFT correspondence, which is a conjectured relationship between open strings and closed strings. So, the aim of this talk is to understand a small piece of superstring theory, specifically in a twisted form. This may be familiar to many people, as some aspects of this have been studied since Witten's work in the 1980s. For example, Witten studied N=2 supersymmetric gauge theories and argued that we can understand a piece of that theory by thinking about Donaldson theory. This idea has been incredibly fruitful. I want to apply something similar to string theory and supergravity. Although I have only been able to access a weak form of the AdS/CFT correspondence, it hints at more interesting non-perturbative results that can be obtained by thinking...
