A Homology Theory for Etale Groupoids [PDF]

open access: yes, 1998
Etale groupoids arise naturally as models for leaf spaces of foliations, for orbifolds, and for orbit spaces of discrete group actions. In this paper we introduce a sheaf homology theory for etale groupoids.

Metrics for generalized persistence modules [PDF]

open access: yes, 2015
We consider the question of defining interleaving metrics on generalized persistence modules over arbitrary preordered sets. Our constructions are functorial, which implies a form of stability for these metrics.

What Is the Validity Domain of Einstein’s Equations? Distributional Solutions over Singularities and Topological Links in Geometrodynamics [PDF]

open access: yes, 2016
The existence of singularities alerts that one of the highest priorities of a centennial perspective on general relativity should be a careful re-thinking of the validity domain of Einstein’s field equations.

Gauge Theories on Deformed Spaces [PDF]

open access: yes, 2010
The aim of this review is to present an overview over available models and approaches to non-commutative gauge theory. Our main focus thereby is on gauge models formulated on flat Groenewold-Moyal spaces and renormalizability, but we will also review ...

Non-locality of zero-bias anomalies in the topologically-trivial phase of Majorana wires [PDF]

open access: yes, 2014
We show that the topologically trivial zero bias peak (ZBP) emerging in semiconductor Majorana wires due to soft confinement exhibits correlated splitting oscillations as a function of the applied Zeeman field, similar to the correlated splitting of the ...

O-minimal cohomology: finiteness and invariance results

open access: yes, 2007
We prove that the cohomology groups of a definably compact set over an o-minimal expansion of a group are finitely generated and invariant under elementary extensions and expansions of the language.

On QCD String Theory and AdS Dynamics [PDF]

open access: yes, 1998
The AdS/CFT correspondence of elementary string theory has been recently suggested as a ``microscopic'' approach to QCD string theory in various dimensions.

Topological Entanglement Entropy, Ground State Degeneracy and Holography [PDF]

open access: yes, 2015
Topological entanglement entropy, a measure of the long-ranged entanglement, is related to the degeneracy of the ground state on a higher genus surface. The exact relation depends on the details of the topological theory.

Riemann-Hilbert correspondence for holonomic D-modules [PDF]

open access: yes, 2015
The classical Riemann-Hilbert correspondence establishes an equivalence between the triangulated category of regular holonomic D-modules and that of constructible sheaves.

Cohomology of generalized configuration spaces

open access: yes, 2019
Let $X$ be a topological space. We consider certain generalized configuration spaces of points on $X$, obtained from the cartesian product $X^n$ by removing some intersections of diagonals.
