Abstract. The aim of this paper is to highlight the superdense unbounded divergence
of a class of product quadrature formulas of interpolatory type on Jacobi
nodes, associated to the Banach space of all real continuous functions defined on
[-1; 1], and to a Banach space of measurable and essentially bounded functions
g : [-1; 1] ! R. Some aspects regarding the convergence of these formulas are
pointed out, too.
