After discussing the role of Liouville equations in both Conformal Geometry and Mathematical Physics, we will explore some of their variational features. In particular we will show the role of the Moser-Trudinger inequality, as well as of some of its improved versions, in characterizing the Euler-Lagrange energy levels of the problems under interest. This description reduces the study of PDEs of Liouville type to topological properties of explicit finite-dimensional objects.
