Abstract
In this lecture I present the basic knowledge needed to understand the properties of the low-frequency spectrum of rotating stars. This spectrum is a mixture of inertial and gravity modes. These modes both have singularities in the limit of vanishing diffusion for a generic container. I explain the nature and the role of these singularities; I also discuss the way these modes can be computed and the actual difficulties that need to be circumvented to get sensible results.
