Title: Equivariant Bredon homology for good real images.
Title: Equivariant Bredon homology for good real images.
Speaker: Ignacio Breva Ribes (Universitat de València, Spain)
Abstract: A complex map-germ admits a good real perturbation if the homology appearing in the discriminant of a stabilization can be detected by a real representative. Smith theory, in particular Floyd's theorem, provides a useful tool to study this phenomena by relating the sum of ranks in homology of a given space to that of its set of fixed points by the action of a finite group. We explain a generalization of Floyd's theorem to the equivariant case based on the notes of Putman via Bredon coefficient systems, and show applications to the problem of good real images (i.e., good real perturbations of map-germs with target dimension greater than source dimension). This is joint work with Roberto Giménez Conejero.

Dedicated to the memory of
Maria Aparecida Soares Ruas - Cidinha
The Brazilians Singularity Theory Webinar of this semester will be dedicated to the memory of Maria Aparecida Soares Ruas (Cidinha). Her trajectory deeply marked the development of Singularity Theory in Brazil and worldwide, training generations of mathematicians and consolidating research groups that today continue her legacy.
This special series will feature talks by her collaborators, who will present results and perspectives related to her contributions, celebrating the strength and vitality of her work.
