Second order partial differential equations.

      Аннотация: This book is a natural continuation of the volumes "Linear differential equations. Classical and modern theory" and "First order partial differential equations. Hamilton-Jacobi theory", published recently by the same authors in LAMBERT Academic Publishing. Now the second order PDEs are studied, as well as their relationship with the mean properties and maximum principles. This volume and the two preceding ones reflect the point of view and the experience of the first author on these subjects. The book is devoted to high-level students, Master students, professors, engineers and any reader interested in this field.
