The Circle Problem on Surfaces of Variable Negative Curvature.
The Conley index and countable decompositions of invariant sets
We define a new cohomological index of Conley type associated to any bi-infinite sequence of neighborhoods that satisfies a certain isolation condition. We use this index to study the chaotic dynamics on invariant sets which decompose as countable unions of pairwise disjoint (mod 0) compact pieces.
