THE COMMON HILBERT SERIES FOR SOME DIFFERENTIAL SYSTEMS WITH HOMOGENEOUS NONLINEARITIES OF ODD DEGREE

Abstract

The Hilbert series for Sibirsky graded algebras of differential systems still now were examined
using a generalized Sylvester method. These series have a special importance for some problems of
qualitative theory of differential systems. For example, a problem related to the Hilbert series of differential
systems is to determine relationships between them. Before finding some relations between Hilbert series,
generalized or ordinary, it is necessary to build these Hilbert series. The article proposes the construction
of Hilbert series of Sibirsky graded algebras using the residue method.
