Analytic and Geometric Study of Stratified Spaces: Contributions to Analytic and Geometric Aspects (Lecture Notes in Mathematics)
The book provides an introduction to stratification theory leading the reader up to modern research topics in the field. The first part presents the basics of stratification theory, in particular the Whitney conditions and Mather's control theory, and introduces the notion of a smooth structure. Moreover, it explains how one can use smooth structures to transfer differential geometric and analytic methods from the arena of manifolds to stratified spaces. In the second part the methods established in the first part are applied to particular classes of stratified spaces like for example orbit spaces. Then a new de Rham theory for stratified spaces is established and finally the Hochschild (co)homology theory of smooth functions on certain classes of stratified spaces is studied. The book should be accessible to readers acquainted with the basics of topology, analysis and differential geometry..

Survival of the Knitted: Immigrant Social Networks in a Stratified World
Through this ethnography of West Indian social networks in New York, London, and the West Indies, Vilna Bashi shows how migrant life is patterned, structured, and regulated to provide critical financial and emotional support. She develops an important new general model of transnational immigrant network organization, the “hub and spoke” model, in which select veteran migrants (hubs) act as migration experts and send repeatedly for newcomers (spokes).

Survival of the Knitted details the ongoing importance of networks throughout the resettlement process. Network hubs use their connections and reputations to find jobs for immigrants and to influence their housing choices. They shape the migrants’ experience of racial hierarchies and social stratification in a new country. As Bashi expertly shows, geographic mobility is a vehicle for socioeconomic and cultural mobility, but in ways more complex and network-dependent than the standard migration story would tell.

Topological Invariants of Stratified Spaces (Springer Monographs in Mathematics)

The central theme of this book is the restoration of Poincaré duality on stratified singular spaces by using Verdier-self-dual sheaves such as the prototypical intersection chain sheaf on a complex variety.

After carefully introducing sheaf theory, derived categories, Verdier duality, stratification theories, intersection homology, t-structures and perverse sheaves, the ultimate objective is to explain the construction as well as algebraic and geometric properties of invariants such as the signature and characteristic classes effectuated by self-dual sheaves.

Highlights never before presented in book form include complete and very detailed proofs of decomposition theorems for self-dual sheaves, explanation of methods for computing twisted characteristic classes and an introduction to the author's theory of non-Witt spaces and Lagrangian structures.
