| Summary: | The linearizability (or isochronicity) problem is one of the open problems for polynomial differential systems which is far to be solved in general. A progressive way
to find necessary conditions for linearizability is to compute period constants. In this
paper, we are interested in the linearizability problem of p : −q resonant degenerate
singular point for polynomial differential systems. Firstly, we transform degenerate
singular point into the origin via a homeomorphism. Moreover, we establish a new recursive algorithm to compute the so-called generalized period constants for the origin
of the transformed system. Finally, to illustrate the effectiveness of our algorithm, we
discuss the linearizability problems of 1 : −1 resonant degenerate singular point for a
septic system. We stress that similar results are hardly seen in published literatures
up till now. Our work is completely new and extends existing ones. |
