We extend to this case Levin's theorem on a connection between the Jessen function, secular constant, and the Phragmen-Lindelof indicator. Then we obtain a multidimensional version of Picard's theorem on exceptional values for our class.16 pagesComplex VariablesClassical Analysis and ODEs32A60: 42A75text
