| Abstract: | Lecture 2-3: We discuss the general problem of constructing an algebraic moduli of objects in derived categories. We will present a first solution to this problem by stating the existence of an algebraic space of compact and simple objects in a nice enough dg-category. We provide applications of the existence a such a moduli space in the study of derived category of algebraic varieties. In a second part, we study the existence of a moduli space for non necessarily simple objects, and state the existence of an algebraic (higher) stack classifying all compact objects in a nice dg-category. As an application we present the construction of Hall algebras in the derived setting by means of geometric methods. |
