English abstract:
This paper deals with the collocation method applied to solve systems of singular linear ordinary differential equations with variable coefficient matrices and unsmooth inhomogeneities. The classical stage convergence order is shown to hold for the piecewise polynomial collocation applied to boundary value problems with time singularities of the first kind provided that their solutions are appropriately smooth. The question of the existence and uniqueness of solutions to the analytical problems have been investigated in the first part of the paper - On singular BVPs with unsmooth data. Part1: Analysis of the linear case with variable coefficient matrix. The convergence theory is illustrated by numerical examples.

Keywords:
