In this paper we consider an over-determined Cauchy problem for the Helmholtz equation in a semifinite domain with a piecewise smooth curvilinear boundary. Applying the Fourier transform method in the space of slow-growth distributions, we establish necessary and sufficient solvability conditions which connect the boundary functions. We construct integral representations of solutions.
Keywords: over-determined Cauchy problem, Helmholtz equation, space of slow-growth distributions.
Mots-clés : Fourier transform
