The Rational Higher Structure of M-theory | | Domenico Fiorenza

7 Mar 2019 | | Abstract: | We review how core structures of string/M-theory emerge as higher structures
in super homotopy theory; namely from systematic analysis of the brane bouquet
of universal invariant higher central extensions growing out of the superpoint.
Since super homotopy theory is immensely rich, to start with we consider this
in the rational/infinitesimal approximation which ignores torsion-subgroups in
brane charges and focuses on tangent spaces of super space-time. Already at
this level, super homotopy theory discovers all super $p$-brane species, their
intersection laws, their M/IIA-, T- and S-duality relations, their black brane
avatars at ADE-singularities, including their instanton contributions, and,
last not least, Dirac charge quantization: for the D-branes it recovers twisted
K-theory, rationally, but for the M-branes it gives cohomotopy cohomology
theory. We close with an outlook on the lift of these results beyond the
rational/infinitesimal approximation to a candidate formalization of
microscopic M-theory in super homotopy theory. | | Source: | arXiv, 1903.2834 | | Services: | Forum | Review | PDF | Favorites | |
