Eléments de la méthode de forcing dans quelques travaux de N. N. Lousin. (French) [Elements of the method of forcing in some papers of N. N. Luzin] Amphora, 469–479, Birkhäuser, Basel, 1992.
Fedor Medvedev has claimed the following:
P. Cohen, who proved the independence of the axiom of choice and of the generalized continuum hypothesis by the method of forcing, did not invent this method, but discovered it in the works of his predecessors. The aim of the paper is to indicate some elements of the method in the works of N. N. Luzin.
I could find the paper, but it is in French, and so I could not read it.
Does anyone know how the work of Luzin is related to forcing?
