Parity as Z2 ‐valued spectral flow [PDF]
This note is about the topology of the path space of linear Fredholm operators on a real Hilbert space. Fitzpatrick and Pejsachowicz introduced the parity of such a path, based on the Leray–Schauder degree of a path of parametrices.

Spectral flow in 3D flat spacetimes [PDF]
In this paper we investigate spectral flow symmetry in asymptotically flat spacetimes both from a gravity as well as a putative dual quantum field theory perspective.

Spectral flow for nonunital spectral triples [PDF]
We prove two results about nonunital index theory left open in a previous paper. The first is that the spectral triple arising from an action of the reals on a ${{C}^{*}}$ -algebra with invariant trace satisfies the hypotheses of the nonunital local ...

Asymptotic spectral flow [PDF]
In this paper we study the asymptotic behavior of the spectral flow of a one-parameter family $$\{D_s\}$$ { D s } of Dirac operators acting on the spinor bundle S twisted by a vector bundle E of rank k , with the parameter $$s\in [0,r]$$ s ∈ [ 0 , r ...

Recently we showed that the spectral flow acting on the N=2 twisted topological theories gives rise to a topological algebra automorphism. Here we point out that the untwisting of that automorphism leads to a spectral flow on the untwisted N=2 super-conformal algebra which is different from the usual one.

Spectral flow for pair compatible equipartitions [PDF]
We show that a recent spectral flow approach proposed by Berkolaiko–Cox–Marzuola for analyzing the nodal deficiency of the nodal partition associated to an eigenfunction can be extended to more general partitions.

Sphalerons, spectral flow, and anomalies [PDF]
The topology of configuration space may be responsible in part for the existence of sphalerons. Here, sphalerons are defined to be static but unstable finite-energy solutions of the classical field equations. Another manifestation of the nontrivial topology of configuration space is the phenomenon of spectral flow for the eigenvalues of the Dirac ...

Spectral flow cytometry identifies distinct nonneoplastic plasma extracellular vesicle phenotype in glioblastoma patients. [PDF]
Background Glioblastoma (GBM) is the most common malignant brain tumor and has a poor prognosis. Imaging findings at diagnosis and in response to treatment are nonspecific. Developing noninvasive assays to augment imaging would be helpful.

Multicompartmental analysis of the murine pulmonary immune response by spectral flow cytometry.
Studies of pulmonary inflammation require unique considerations due to the complex structure and composition of the lungs. The lungs have multiple compartments and diverse immune cell populations, with inherently high autofluorescence, and are involved ...
