Since in the zero fermion mass limit the AVV triangle is identical to an AAA triangle, I knew already in unpublished notes dating from the late summer of 1968 that the AAA triangle would also have an anomaly. We consider the hypothesis that the C-field 4-flux and 7-flux forms in M-theory are in the image of the non-abelian Chern character map from the non-abelian generalized cohomology theory called J-twisted Cohomotopy theory. It is shown that each species individually gives the correct consistent anomaly. OSTI.GOV Journal Article: Novel facets of the Non-abelian anomaly Consequently, the effective field theory displays U(1)×SU(2) non-Abelian anomalies, yielding the anomalous Hall effect, its non-Abelian generalization, and various chiral conductivities. flavored, supersymmetric, and dark matter model building typically subdivide into two classes differentiated by the simple restrictions they impose on the number of fields transforming under certain irreducible representations of the relevant groups. We derive anomaly constraints for Abelian and non-Abelian discrete symmetries using the path integral approach.

Such a tenuous symmetry is said to be "anomalous," beset by a "quantum symmetry anomaly."

We further re-derive the conditions for Abelian discrete symmetries to be anomaly-free, using the path integral method. OSTI.GOV Journal Article: Non-Abelian anomaly and lattice-fermionic regularizations Title: Non-Abelian anomaly and lattice-fermionic regularizations Full Record We survey anomalies of discrete symmetries in heterotic orbifolds and find a new relation between such anomalies and the socalled ‘anomalous ’ U(1).
In total, however, the anomaly is canceled by opposite-handed species. Abstract: J54.00009: Non-Abelian anomalies in multi-Weyl semimetals Abstract . The relationship between the phenomenon of species doubling on the lattice and the Abelian anomaly is generalized to the case of the non-Abelian anomaly. A mathematical model for physical phenomena may possess a symmetry when its dynamics is analyzed in terms of unquantized, commuting variables, but the symmetry may disappear when the dynamics is quantized and analysis is performed in terms of non-commuting quantum variables.
This derivation allows for an alternative, perhaps more intuitive …
Such an SU(2) field preserves certain crystalline symmetry (fourfold rotational or C4 in our construction), but breaks the Lorentz symmetry, resulting in nonlinear band spectra, namely, E∼(p2x+p2y)n/2, but E∼|pz|, for example, where momenta p is measured from the Weyl nodes. These predictions are also supported from a strongly coupled (holographic) description of MWSMs.
