Research links
Slides from my 2020
talk at the annual AMS meeting, "A numerical approach to Chern numbers
and unbounded Fredholm modules". I had issues embedding the videos, so
these are separate files:
edge mode around defect,
edge mode around clean system,
edge mode for square with disorder,
A website promoting the localizer in
operator theory and quantum mechanics.
Supplemental files to
"Surfaces and hypersurfaces as the joint spectrum of matrices" by DeBonis, Loring and Sverdlov.
Slides from my 2019 talk at CMO Oaxaca,
workwhop on Topological Phases of Interacting Quantum Systems,
talk titled "The spectral localizer for estimating bulk gaps and calculating Ktheory".
ArXiv feed. Preprints of
my papers are on the Arxiv and they are not always close to the final
version.
CV with full list of publications.
My
user page Math Overflow.
My writings and citations listed at Google Scholar.
My ORC ID and another listing of some of my writings.
My dissertation,
The Torus and Noncommutative Topology.
Et Cetera.
