Caractérisation des variétés homologiques à l'aide des invariants d'homologie d'intersection
La conférence de J. P. Brasselet au Symposium de Varsovie a eu pour thème les problèmes actuels de l’homologie d’intersection. Nous en présentons ici l’un des aspects, résultat d’un travail commun réalisé dans le cadre du programme Procope et pendant lequel le second auteur a été chercheur associé au CNRS.

Cell-like resolutions of polyhedra by special ones
Suppose that P is a finite 2-polyhedron. We prove that there exists a PL surjective map f:Q → P from a fake surface Q with preimages of f either points or arcs or 2-disks. This yields a reduction of the Whitehead asphericity conjecture (which asserts that every subpolyhedron of an aspherical 2-polyhedron is also aspherical) to the case of fake surfaces. Moreover, if the set of points of P having a neighbourhood homeomorphic to the 2-disk is a disjoint union of open 2-disks, and every point of P...
