Abstract: The even asymptotic decomposition of the external Dirichlet’s problem is found with Laplace equation outside of thin disk in three-dimensional space. The small parameter is a thickness of the disk. Physical interpretation given problems is the flow of the disk by a laminar stream of a liquid.

Keywords: value boundary problem, Laplace equation, asymptotic decomposition, thin disk, laminar stream, flow.
