Homogeneity and projective equivalence of differential equation fields
We propose definitions of homogeneity and projective equivalence for systems of ordinary differential equations of order greater than two, which allow us to generalize homogeneous differential equation fie...

Equivalence and symmetries of second--order differential equations
In this article we investigate the equivalence of underdetermined differential equations and differential equations with deviations of second order with respect{$bar z=bar z(bar x)=M(x)+z(x).$} Our main ai...

On square integrable solutions of the third order linear differential equations
We study the problem of asymptotic equivalence in the space of square integrable functions for the linear third order differential equation and the Appel equation. The sufficient conditions to be all solutions of t...

A recursion operator for the universal hierarchy equation via Cartan's method of equivalence
We apply Cartan's method of equivalence to find a Backlund autotransformation for the tangent covering of the universal hierarchy equation. The transformation provides a recursion operator for symmetries of this equation....

Principal solutions and minimal sets of quasilinear differential equations
Principal solutions of the nonoscillatory half-linear differential equation are investigated and equivalency between the limit, Riccati and integral characterizations of these solutions is proved. The notion of principal so...

Divergent CR-equivalences and meromorphic differential equations
Using the analytic theory of differential equations, we construct, in any positive CR-dimension and CR-codimension, examples of formally but not holomorphically equivalent real-analytic CR-submanifolds in complex space....

An asymptotic formula for decreasing solutions to coupled nonlinear differential systems
of a sub-homogeneous system of two second order quasilinear ordinary differential equations. This result is obtained as an application of an asymptotic equivalence of application to a fourth order nonlinear differentia...
