Abstract(#br)We consider functions f ( z ) ( f (0) = 1, | z | < 1) from spaces endowed with mixed norm; in particular, the Bergmann-Dzharbashian space, with zeroes z k ( f ) (| z 1 ( f )| ≤ | z 2 ( f )| ≤ ...). We construct examples of such functions f that the products $$\pi n(f) = \left( {\left| {...
