The Equivariant L-Class of Pseudomanifolds
Markus Banagl
We construct an equivariant L-class for orientation preserving actions of a compact Lie group on a Whitney stratified compact oriented pseudomanifold that satisfies the Witt condit…

Link Bundles and Intersection Spaces of Complex Toric Varieties
Markus Banagl, Shahryar Ghaed Sharaf
There exist several homology theories for singular spaces that satisfy generalized Poincaré duality, including Goresky-MacPherson's intersection homology, Cheeger's cohomolog…

Transfer and the Spectrum-Level Siegel-Sullivan KO-Orientation for Singular Spaces
Markus Banagl
Integrally oriented normally nonsingular maps between singular spaces have associated transfer homomorphisms on KO-homology at odd primes. We prove that such transfers preserve Sie…
