Brav—Dyckerhoff also introduced a relative notion of such, which allows one to recover Verdier duality for manifolds with boundaries. If now X is equipped with a (nice enough) finite stratification P, we show that there exists a Calabi—Yau structure on the k-..." current

In this talk, after an introduction into the homotopy theory of stratified spaces, I want to talk about an explicit presentation of this proclaimed equivalence in terms of a Quillen equivalence using Lurie’s construction of the infinity-category of exit-pa..." current

In this talk, I will introduce the notion of isovariant G-Poincaré spaces, a homotopical notion interpolating between closed smooth G-manifolds and G-Poincaré spaces. The main result shows that, for a periodic finite group G and under suitable codimension hypothesis, the space of isovariant structures on a G-Poincaré space is highly connected. This is a useful tool for constructing m..." current
