前言/序言

  The theory of differential equations has two aspects of investigation,namely local and global,no matter whether the equations arise from applied problems of physics and mechanics or from abstract speculations (which is rather frequent in modern mathematics).The local aspect is characterized by dealing with the inner structure of a family of solutions and its investigation in a neighborhood of a certain point.The global approach deals with solutions definedin some domain and having a given behavior on its boundary.
  It would certainly be erroneous to oppose these directions to each other.However,it is no good to ignore the differences in approaches either.While the global approach necessitates the functional analytic apparatus,the local viewpoint allows one to get along with algebraic means only.A brilliant example of a profound local consideration is the famous Cauchy-Kovalevskaya theorem which is,in fact,an algebraic statement.Moreover,it is an easy matter to notice that the theory of boundary value problems also makes an essential application of various algebraic properties of the whole family of solutions. Therefore,the local aspect of the algebraic theory of differential equations is quite vital.
