Geometry Search for the term Geometry in any field. Queries are case-independent.
Funct* Wildcard queries are specified by * (e.g. functions, functorial, etc.). Otherwise the search is exact.
"Topological group" Phrases (multi-words) should be set in "straight quotation marks".

On the dimension of the compact invariant sets of certain non-linear maps. (English) Zbl 0544.58014

Let E be a Banach space, UE be an open set and f:UE be a C 1 -map. It is shown that if ΛE is a compact set such that f(Λ)Λ and for every xΛ the derivative D x f can be decomposed as a sum of a compact map and a contraction, then the limit capacity (and moreover the Hausdorff dimension) of Λ is finite.
