# Schreiber TED K-theory of Cohomotopy moduli spaces and Anyonic Topological Order

a talk that I have given:

Abstract: It is largely folklore that:

1. topological K-theory in its full twisted & equivariant & differential (TED) refinement classifies stable D-branes in string theory, as well as non-interacting topological insulator phases in condensed matter theory;
2. some non-perturbative/strongly-interacting enhancement of this classification is needed to account for M-branes in string theory as well as for interacting topological order in condensed matter theory

but:

1. full TED K-theory has never quite been formulated before;
2. its M-theoretic/strongly-interacting enhancement has remained elusive.

This talk surveys:

1. our Hypothesis H about its M-theoretic/strongly-interacting enhancement:

instead of applying TED-K to the spacetime orbifold/Brillouin torus directly, it needs to be applied to the corresponding twisted Cohomotopy moduli space;

2. how the resulting theory explains the nature of defect branes (such as D7-branes and “M3-branes”) in M-/F-theory as well as anyonic topological order in condensed matter theory.

This is a joint project with Hisham Sati
