Mapping Spaces and Homology Isomorphisms

چکیده
Let Map(K,X) denote the space of pointed continuous maps from a finite cell complex K to a space X. Let E∗ be a generalized homology theory. We use Goodwillie calculus methods to prove that under suitable conditions on K and X, Map(K,X) will send an E∗–isomorphism in either variable to a map that is monic in E∗ homology. Interesting examples arise by letting E∗ be K–theory, the finite complex K be a sphere, and the map in the X variable be an exotic unstable Adams map between Moore spaces.

Juvitop on Bousfield Localization
Homotopy theory studies topological spaces up to homotopy, so it must study the functor π∗ : Top → Π−algebras. Passage to the homotopy category is declaring π∗-isomorphisms to be isomorphisms. Because this functor is difficult to compute, one way to do homotopy theory is to study simpler functors which also map to graded abelian categories, e.g. πQ ∗ , H∗(−;Z), K∗, or more generally E∗ for E so...
متن کاملFunctoriality and duality in Morse-Conley-Floer homology
In [13] a homology theory –Morse-Conley-Floer homology– for isolated invariant sets of arbitrary flows on finite dimensional manifolds is developed. In this paper we investigate functoriality and duality of this homology theory. As a preliminary we investigate functoriality in Morse homology. Functoriality for Morse homology of closed manifolds is known [1, 2, 3, 8, 14], but the proofs use isom...
متن کاملSome aspects of cosheaves on diffeological spaces
We define a notion of cosheaves on diffeological spaces by cosheaves on the site of plots. This provides a framework to describe diffeological objects such as internal tangent bundles, the Poincar'{e} groupoids, and furthermore, homology theories such as cubic homology in diffeology by the language of cosheaves. We show that every cosheaf on a diffeological space induces a cosheaf in terms of t...
متن کاملThe Künneth Formula for Nuclear Df -spaces and Hochschild Cohomology
We consider complexes (X , d) of nuclear Fréchet spaces and continuous boundary maps dn with closed ranges and prove that, up to topological isomorphism, (Hn(X , d)) ∗ ∼= H(X ∗, d∗), where (Hn(X , d)) ∗ is the strong dual space of the homology group of (X , d) and H(X ∗, d∗) is the cohomology group of the strong dual complex (X ∗, d∗). We use this result to establish the existence of topologica...
متن کاملIsomorphisms in `1-homology
Taking the `1-completion and the topological dual of the singular chain complex gives rise to `1-homology and bounded cohomology respectively. Unlike `1-homology, bounded cohomology is quite well understood by the work of Gromov and Ivanov. We derive a mechanism linking isomorphisms on the level of homology of Banach chain complexes to isomorphisms on the level of cohomology of the dual Banach ...
