Renormalization of Chern-Simons Wilson Loops via Flux Quantization in Cohomotopy
Hisham Sati, Urs Schreiber
In the practice of physics model building, the process of renormalization, resummation, and anomaly cancellation is to incrementally repair initially ill-defined Lagrangian quantum…
The M-algebra completes the hierarchy of Super-Exceptional Tangent Spaces
Grigorios Giotopoulos, Hisham Sati, Urs Schreiber
The conjectured symmetries of M-theory famously involve (1.) brane-extended super-symmetry (the M-algebra) and (2.) exceptional duality-symmetry (the -algebra);…
Anyons on M5-Probes of Seifert 3-Orbifolds via Flux Quantization
Hisham Sati, Urs Schreiber
We observe that there is a rigorous derivation of (abelian) anyonic quantum states, hence of "topological order", on the 1+2-dimensional fixed locus of M5-probes wrapped over a tri…
The Hidden M-Group
Grigorios Giotopoulos, Hisham Sati, Urs Schreiber
Following arguments that the (hidden) M-algebra serves as the maximal super-exceptional tangent space for 11D supergravity, we make explicit here its integration to a (super-Lie) g…
Holographic M-Brane Super-Embeddings
Grigorios Giotopoulos, Hisham Sati, Urs Schreiber
Over a decade before the modern formulation of AdS/CFT duality, Duff et al. had observed a candidate microscopic explanation by identifying the CFT fields with fluctuations of prob…
Flux Quantization
Hisham Sati, Urs Schreiber
Flux- and charge-quantization laws for higher gauge fields of Maxwell type -- e.g. the common electromagnetic field (the "A-field") but also the B-, RR-, and C-fields considered in…
