De Rham intersection cohomology for general perversities

Martintxo E. Saralegi-Aranguren

For a stratified pseudomanifold $X$ , we have the de Rham Theorem $ \lau{\IH}{*}{\per{p}}{X} = \lau{\IH}{\per{t} - \per{p}}{*}{X}, $ for a perversity $\per{p}$ verifying $\per{0} \l…

Intersection cohomology of circle actions

Gabriel Padilla, Martintxo Saralegi-Aranguren

A classical result says that a free action of the circle $S^{1}$ on a topological space $X$ is geometrically classified by the orbit space $B$ and by a cohomological class ${H}…

The BIC of a singular foliation defined by an abelian group of isometries

M. Saralegi-Aranguren, R. Wolak

We study the cohomology properties of the singular foliation $\F$ determined by an action $Φ : G \times M \to M$ where the abelian Lie group $G$ preserves a riemannian metric on…
