 But I have to warn you that there will be a complex in my talk, but positivity will ultimately enter. If it enters, it enters in a negative way. You'll see where we get it. So not only that, but this talk will be a complex manifold, an infinite dimensional complex manifold modeled in a lot of spaces. So if we had 50 minutes, I would actually define for me what a complex manifold is. The way it is, I ask you to use your imagination, your sense of analogy. It should surprise that any particular, if there's not much space, infinite dimensional that this talk is, arise from finite dimension, on a finite dimensional complex manifold. So we start with x in finite dimensional, a compact house or space, s. Continuous maps of s to x, perhaps surprising at where we first see such a thing, because okay, s is in a complex manifold, s has nothing to do with a complex structure. This is a complex manifold. For example, let's look at, a space in a complex manifold is c, a complex plane. So there is a complex by a functional s, which is a complex space. It looks like cn. To understand its properties, you look at various mapping spaces into it. And you know, if the topological space is a complex manifold, that you are trying to investigate, your topological space is a complex manifold, then it looks like a waste not to try to exploit that this mapping space itself is a complex manifold. So in topology, of course, there is also another motivation, which is perhaps, there is a connection with theoretical physics, field theories. Often times fields believe exactly as far as the prongian which governs taffold ocean. This mapping space, it's not these maps. We looked at differentiable or several times differentiable maps assuming that s itself is a manifold. It's perhaps easier by manipulating the derivatives and all that to write on board. It depends on s. Continuous maps should explain in some ways why it is. It is somewhat analogous to the monotremic theorem, which guarantees that it is a homomorphic germ. And if this germ can be a single-dialed form, so the monotremic theorem, if this space c was in general resolved, it goes back to the 1970s. Interestingly, the assumption this is right to extend it to the second or the right one, but also that boundedness can, for example, the continuous function is first solved in one solution. For us, the entire second rule instead, we notice that more bounded boreal functions instead we want you to also look at and it turns out that this is also a complex manifold of which c is some kind of effect. Here, I would say that this is a relief for this. Maybe this quantifier is not the right symbol to use here, because even here this extension is not unique, but as a construction, similarly, there is a certain construction that gives an extension. That is, you need to determine if I know what these values are and these values are probably points in the next. So what that means is that this is vital, so now this is not only complex, but simply connected that these extensions are both single-dialed because this is simply connected space. And secondly,
