Variations of rational higher tangential structures
Hisham Sati, Matthew Wheeler
The study of higher tangential structures, arising from higher connected covers of Lie groups (String, Fivebrane, Ninebrane structures), require considerable machinery for a full d…
T-Duality from super Lie n-algebra cocycles for super p-branes
Domenico Fiorenza, Hisham Sati, Urs Schreiber
We compute the -theoretic dimensional reduction of the F1/D-brane super -cocycles with coefficients in rationalized twisted K-theory from the 10d type IIA an…
Rational sphere valued supercocycles in M-theory and type IIA string theory
Domenico Fiorenza, Hisham Sati, Urs Schreiber
We show that supercocycles on super -algebras capture, at the rational level, the twisted cohomological charge structure of the fields of M-theory and of type IIA string…
Spectral sequences in smooth generalized cohomology
Daniel Grady, Hisham Sati
We consider spectral sequences in smooth generalized cohomology theories, including differential generalized cohomology theories. The main differential spectral sequences will be o…
Primary operations in differential cohomology
Daniel Grady, Hisham Sati
We characterize primary operations in differential cohomology via stacks, and illustrate by differentially refining Steenrod squares and Steenrod powers explicitly. This requires a…
Twisted iterated algebraic K-theory and topological T-duality for sphere bundles
John A. Lind, Hisham Sati, Craig Westerland
We introduce a periodic form of the iterated algebraic K-theory of ku, the (connective) complex K-theory spectrum, as well as a natural twisting of this cohomology theory by higher…
