On topological cyclic homology

T Nikolaus, P Scholze - 2018‏ - projecteuclid.org
Topological cyclic homology is a refinement of Connes–Tsygan's cyclic homology which
was introduced by Bökstedt–Hsiang–Madsen in 1993 as an approximation to algebraic K …

Twistorial cohomotopy implies Green–Schwarz anomaly cancellation

D Fiorenza, H Sati, U Schreiber - Reviews in Mathematical Physics, 2022‏ - World Scientific
We characterize the integral cohomology and the rational homotopy type of the maximal
Borel-equivariantization of the combined Hopf/twistor fibration, and find that subtle relations …

[HTML][HTML] Nilpotence and descent in equivariant stable homotopy theory

A Mathew, N Naumann, J Noel - Advances in Mathematics, 2017‏ - Elsevier
Let G be a finite group and let F be a family of subgroups of G. We introduce a class of G-
equivariant spectra that we call F-nilpotent. This definition fits into the general theory of …

[کتاب][B] The Character Map in Non-abelian Cohomology: Twisted, Differential, and Generalized

D Fiorenza, H Sati, U Schreiber - 2024‏ - World Scientific
To set the scene, we begin here by reviewing basics of homotopy theory via model category
theory [Quillen (1967)](review in [Hovey (1999)][Hirschhorn (2003)][Lurie (2009a), A. 2]) and …

Topological Quantum Gates in Homotopy Type Theory

DJ Myers, H Sati, U Schreiber - Communications in Mathematical Physics, 2024‏ - Springer
Despite the plausible necessity of topological protection for realizing scalable quantum
computers, the conceptual underpinnings of topological quantum logic gates had arguably …

The chromatic nullstellensatz

R Burklund, TM Schlank, A Yuan - arxiv preprint arxiv:2207.09929, 2022‏ - arxiv.org
We show that Lubin--Tate theories attached to algebraically closed fields are characterized
among $ T (n) $-local $\mathbb {E} _ {\infty} $-rings as those that satisfy an analogue of …

Short-range entanglement and invertible field theories

DS Freed - arxiv preprint arxiv:1406.7278, 2014‏ - arxiv.org
Quantum field theories with an energy gap can be approximated at long-range by
topological quantum field theories. The same should be true for suitable condensed matter …

Units of ring spectra, orientations, and Thom spectra via rigid infinite loop space theory

M Ando, AJ Blumberg, D Gepner… - Journal of …, 2014‏ - academic.oup.com
We extend the theory of Thom spectra and the associated obstruction theory for orientations
in order to support the construction of the string orientation of, the spectrum of topological …

Bordism for the 2-group symmetries of the heterotic and CHL strings

A Debray - Higher structures in topology, geometry, and physics, 2024‏ - books.google.com
In the presence of a nonzero B-field, the symmetries of the E8× E 8 heterotic string form a 2-
group, or a categorified group, as do the symmetries of the CHL string. We express the …

Proper orbifold cohomology

H Sati, U Schreiber - arxiv preprint arxiv:2008.01101, 2020‏ - arxiv.org
The concept of orbifolds should unify differential geometry with equivariant homotopy theory,
so that orbifold cohomology should unify differential cohomology with proper equivariant …
