On the topological structure of the set of singularities for interpolatory product integration rules

This paper highlights the phenomenon of double condensation of singularities for interpolatory product integration rules, related to a class of projection operators (including Lagrange and Sturm-Liouville projections), associated to the Banach space of real continuous functions defined on a compact set in RR of positive measure.
