Izv. Math. 61, No. 4, 795-812 (1997); translation from Izv. Ross. Akad. Nauk, Ser. Mat. 61, No. 4, 119-136 (1997).
Since a pioneer theorem of Fabry in 1896, many papers have been devoted to give conditions under which an analytic function defined on $$| z | < 1$$ by a power series cannot be analytically continued into the region $$| z| >1$$, across any arc of the circle $$| z| =1$$. The present paper enlarges the known class of power series that cannot be analytically continued in the above sense. Complete proofs are given and the paper presents a general picture of the history of the subject.
