Poincar E Sheaves on Topological Spaces
نویسنده
چکیده
We deene the notion of a Poincar e complex of sheaves over a topological space. Global surgery invariants of spaces and maps are expressed as the assembly of locally deened surgery invariants. For simplicial complexes we recover the theory of Poincar e cycles of Ranicki. For more general spaces we obtain local surgery invariants in the absence of triangulations.

Some 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 کاملOn Fuzzy $e$-open Sets, Fuzzy $e$-continuity and Fuzzy $e$-compactness in Intuitionistic Fuzzy Topological Spaces
The purpose of this paper is to introduce and study the concepts of fuzzy $e$-open set, fuzzy $e$-continuity and fuzzy $e$-compactness in intuitionistic fuzzy topological spaces. After giving the fundamental concepts of intuitionistic fuzzy sets and intuitionistic fuzzy topological spaces, we present intuitionistic fuzzy $e$-open sets and intuitionistic fuzzy $e$-continuity and other results re...
متن کاملA Remark on Sheaf Theory for Non-hausdorr Manifolds
Much of sheaf theory can be developed for arbitrary topological spaces. This applies, for example , to the deenition of 'sheaf' itself, to the existence of injective resolutions, to the properties of the operations f and f associated to a continuous map f : Y ?! X, etc, etc. On the other hand, there is a very basic part of the theory which seems to depend crucially on the Hausdorr property (tog...
متن کاملSheaves over Topological Spaces
The category of sheaves over a topological space has a rich internal logic, but they also have a very rich geometric interpretation. In these notes I review the basic notions of sheaves over topological spaces, with an emphasis on the geometry of sheaves. I prove that sheaves are toposes, present the proof of the equivalence between the category of sheaves over X and the set of local homeomorph...
متن کاملFibrations and Homotopy Colimits of Simplicial Sheaves
We show that homotopy pullbacks of sheaves of simplicial sets over a Grothendieck topology distribute over homotopy colimits; this generalizes a result of Puppe about topological spaces. In addition, we show that inverse image functors between categories of simplicial sheaves preserve homotopy pullback squares. The method we use introduces the notion of a sharp map, which is analogous to the no...
