Abstract

Recently Denisov (aka Dennisov) (Proc. Amer. Math. Soc.) has proved the following remarkable extension of Rakhmanov's theorem (Math. USSR-Sb. 46 (1983) 105: Russian Original, Mat. Sb. 118 (1982) 104) (see also (Mate et al., Constr. Approx., 1 (1985) 63: Nevai, J. Approx. Theory 65 (1991) 322)) which was conjectured in (Nevai, in: Approximation Theory IV. Vol. II, Academic Press, New York. 1989, pp. 449-489, (Conjecture 2.7, p. 453).
