The differential operators and multiplicity of singular points for polynomial differential system. (English)

Authors: Baltag Valeriu, Vulpe Nicolae


Differential operators acting in initial system coefficient space are constructed for two-dimensional autonomous polynomial systems of differential equations. Using them coefficient conditions for the sum of the multiplicities of all the finite singular points as well as for the multiplicity of singular point (0,0) are found.
