Spatial Riemann problem for analytic functions of two complex variables (Q1969383)

The authors consider a boundary value problem \(A\Phi^{++} +B\Phi^{-+}+ C\Phi^{+-}+D\Phi^{--}=F\) for polydiscs, where the functions \(A,B, C,D,F\) belong for the Wiener algebra. Conditions to existence of a finite number of solutions and a finite number of solvability conditions are established.
