Systems of Ordinary Differential Equations with a Small Parameter,In this chapter we construct an analogue of the matrix perturbation theory for systems of the form . where . ., or, in vector notation, ..

Reconstruction,In various problems we must employ variable transformations degenerate at e ε = 0. One such example is the case of a nilpotent . considered in Sections 1.5 and 2.5, where a special (shearing) transformation reconstructs . so that another operator, different from ., becomes the leading one.
