The author obtained geometrical characteristics of a number of classes of systems of differential equations of the second order distinguished on the basis of two kinds of connectivities in fibration of reters. The work is performed by means of the theoretical and group method. The system of differential equations is considered as an equation of some surface in the space of tangent elements.
Получены геометрические характеристики ряда классов систем дифференциальных уравнений второго порядка, выделенных на основе двух видов связностей в расслоении ретеров. Работа выполнена теоретико-групповым методом. Система дифференциальных уравнений рассматривается как уравнение некоторой поверхности в пространстве касательных элементов.
