The Conley index and the critical groups via an extension of Gromoll-Meyer theory
Słowa kluczowe
Gromoll-Meyer pairs, Conley index pairs, dynamically isolated set, isolating invariant neighbourhoods, invariance properties of the Conley indexAbstrakt
We investigate, in a variational setting, the relationship between the Gromoll-Meyer pairs of {\it a dynamically isolated critical set}\/ and the Conley index pairs of its {\it isolating invariant neighbourhoods}. We show that the information given by the critical groups of such a set is equivalent to that given by the Conley index. This allows us to derive - in a non-compact setting - various invariance properties for the Conley index from those of the critical groups, as well as a formula relating the degree of a gradient vector field in an isolating neighbourhood to the Conley index pair associated with it.Pobrania
