Abstract: | Summary A natural class of homotopy methods for solving polynomial systems is considered. It is shown that at least one solution from each connected component of the solution set is obtained. This generalizes the results of previous papers which concentrated on isolated solutions, i.e. connected components with one single point. The number of solution paths ending in a connected component is independent of the particular homotopy in use and defines in a natural way the multiplicity of the connected component. A few numerical experiments illustrate the obtained results. |
