boundary value pioblems can be solved relatively easy with the aid of (4),

the necessary tables for knot types 1). X j . 2j-nn- 1 b and
2), x 2j- n- I b are given. It is shown that for an application

of (4) to the solution of integral equations there appear systems of
equations of a special kind for the approximative solution of which an
algorithm is given. By the example of the boundary value problem
