M/F-theory as -theory

H Sati, U Schreiber - Reviews in Mathematical Physics, 2023 - World Scientific
In the quest for mathematical foundations of M-theory, the Hypothesis H that fluxes are
quantized in Cohomotopy theory, implies, on flat but possibly singular spacetimes, that M …

A heterotic Kodaira-Spencer theory at one-loop

A Ashmore, JJ Murgas Ibarra, DD McNutt… - Journal of High Energy …, 2023 - Springer
A bstract We consider a heterotic version of six-dimensional Kodaira-Spencer gravity
derived from the heterotic superpotential. We compute the one-loop partition function and …

Differential KO-theory: constructions, computations, and applications

D Grady, H Sati - Advances in Mathematics, 2021 - Elsevier
We provide several constructions in differential KO-theory. First, we construct a differential
refinement of the A ˆ-genus and a pushforward leading to a Riemann-Roch theorem. We set …

The classical topological invariants of homogeneous spaces

J Jones, D Rumynin, AR Thomas - arxiv preprint arxiv:2310.14365, 2023 - arxiv.org
We study the homogeneous spaces of a simply connected, compact, simple Lie group $ G $
through the lens of K-theory. Our methods apply equally well to the case where $ G $ is in …

Motivic Hirzebruch class and related topics

S Yokura - Handbook of Geometry and Topology of Singularities …, 2023 - Springer
The motivic Hirzebruch class is a characteristic class “unifying” three distinguished
characteristic homology classes of singular varieties. In this survey we discuss characteristic …
