Title : A brief introduction to differential graded Lie algebras I, II

Abstract : The importance of differential graded Lie algebras goes back at least to Quillen’s rational homotopy theory, which also motivated their applications to deformation theory. Later, such an idea was developed further by Deligne, Drinfeld, and Feigin, and influenced many including Kontsevich and Soibelman. The purpose of these talks is to give a short introduction to the notion of differential graded Lie algebras and its relationship to deformation theory. These talks are intended to be an elementary introduction to the subject, but due to the current nature of it, I’ll say something about the theory of infinitycategories. The first talk will be devoted to exploring some of the fundamentals of differential graded Lie algebras and infinitycategories, and the application to deformation theory will be covered in the later half of the second talk.
