The paper is dealt with the method of transfer of conditions for solving singular boundary value problems for a linear second order differential equation. The method consists in replacing the problem by a sequence of initial value problems.

After a description of the method of transfer of conditions in the regular case, developed by the second author (Rozpravy Ceskosl. Akad. Ved., R. Mat. Prirod. Ved. 83, No.5, 1-134 (1973; Zbl 0276.34009)], the authors present and prove two theorems for the transferred conditions in the singular case. On the basis of these theorems the algorithm for solving singular boundary value problems for a linear differential equation of the second order can be developed easily.

Singular boundary value problems for the considered equation occur in a number of physical problems, e.g. when using the Fourier method for the Poisson equation in polar coordinates, and when solving the eigenvalue problem for the radial Schrödinger equation.
