Summary: | In this article, Conley’s connection matrix theory and a spectral sequence analysis of a filtered Morse chain complex
$(C,{\rm\Delta})$
are used to study global continuation results for flows on surfaces. The briefly described unfoldings of Lyapunov graphs have been proved to be a well-suited combinatorial tool to keep track of continuations. The novelty herein is a global dynamical cancellation theorem inferred from the differentials of the spectral sequence
$(E^{r},d^{r})$
. The local version of this theorem relates differentials
$d^{r}$
of the
$r$
th page
$E^{r}$
to Smale’s theorem on cancellation of critical points. |
