Stratified spaces: joining analysis, topology and geometry. Abstracts from the workshop held December 11--17, 2011. (Q343312)

Summary: For manifolds, topological properties such as Poincaré duality and invariants such as the signature and characteristic classes, results and techniques from complex algebraic geometry such as the Hirzebruch-Riemann-Roch theorem, and results from global analysis such as the Atiyah-Singer index theorem, worked hand in hand in the past to weave a tight web of knowledge. Individually, many of the above results are in the meantime available for singular stratified spaces as well. The 2011 Oberwolfach workshop ``Stratified Spaces: Joining Analysis, Topology and Geometry'' discussed these with the specific aim of cross-fertilization in the three contributing fields.
