Positive Scalar Curvature on Spin Pseudomanifolds: the Fundamental Group and Secondary Invariants [PDF]
, 2021 In this paper we continue the study of positive scalar curvature (psc) metrics on a depth-1 Thom-Mather stratified space $M_\Sigma$ with singular stratum $\beta M$ (a closed manifold of positive codimension) and associated link equal to $L$, a smooth ...

Subelliptic Bourgain-Brezis Estimates on Groups [PDF]
, 2008 We show that divergence free vector fields which belong to L^1 on stratified, nilpotent groups are in the dual space of functions whose sub-gradient are L^Q integrable where Q is the homogeneous dimension of the group.

Harmonic forms on manifolds with edges [PDF]
, 2005 Let $(X,g)$ be a compact Riemannian stratified space with simple edge singularity. Thus a neighbourhood of the singular stratum is a bundle of truncated cones over a lower dimensional compact smooth manifold.

The Novikov conjecture on Cheeger spaces [PDF]
, 2016 We prove the Novikov conjecture on oriented Cheeger spaces whose fundamental group satisfies the strong Novikov conjecture. A Cheeger space is a stratified pseudomanifold admitting, through a choice of ideal boundary conditions, an L2-de Rham cohomology ...

Totally normal cellular stratified spaces and applications to the configuration space of graphs [PDF]
, 2014 The notion of regular cell complexes plays a central role in topological combinatorics because of its close relationship with posets. A generalization, called totally normal cellular stratified spaces, was introduced by the third author by relaxing two ...

Singular Poisson reduction of cotangent bundles [PDF]
, 2005 We consider the Poisson reduced space $(T^*Q)/K$ with respect to a cotangent lifted action. It is assumed that $K$ is a compact Lie group which acts by isometries on the Riemannian manifold $Q$ and that the action on $Q$ is of single isotropy type ...

Quasi-geostrophic modes in the Earth's fluid core with an outer stably stratified layer [PDF]
, 2015 Seismic waves sensitive to the outermost part of the Earth's liquid core seem to be affected by a stably stratified layer at the core-mantle boundary.

Poisson structures on certain moduli spaces for bundles on a surface [PDF]
, 1994 Let $\Sigma$ be a closed surface, $G$ a compact Lie group, with Lie algebra $g$, and $\xi \colon P \to \Sigma$ a principal $G$-bundle. In earlier work we have shown that the moduli space $N(\xi)$ of central Yang- Mills connections, for appropriate ...

First Passage Time in a Two-Layer System
, 1994 As a first step in the first passage problem for passive tracer in stratified porous media, we consider the case of a two-dimensional system consisting of two layers with different convection velocities.

Urban energy exchanges monitoring from space [PDF]
, 2018 One important challenge facing the urbanization and global environmental change community is to understand the relation between urban form, energy use and carbon emissions.
