The talk is devoted to the study of suitable Nystrom Methods, based on global polynomial approximation, for boundary integral equations of second kind. An application to the planar radiosity equation will be given. This approach represents a first step in the study of the spatial radiosity equation, which relates the brightness at points of a surface to the reflectivity and emissivity at such points, and also to the geometric shape of the surface.
