Abstract

We study the Cauchy problem for the Laplace equation in a cylindrical domain with data on a part of its boundary which is a cross-section of the cylinder. On reducing the problem to the Cauchy problem for the wave equation in a complex domain and using hyperbolic theory we obtain explicit formulas for the solution, thus developing the classical approach of Hans Lewy (1927).
