On extended singular set of potentials

We introduce the notion of extended singular set of functions. For a class of functions of Bessel potential type we show that their extended singular set is contained in the set where the potential attains infinite value. The result has been announced and exploited in author's paper: Singular sets of Sobolev functions. // Comptes Rendus de l'Académie des Sciences - Series I - Mathematics. 334 (2002) , 7 ; 539-544
