Cyclicity of all anti-NMHV and $$\hbox {N}^{2}{\mathrm{MHV}}$$ N2MHV tree amplitudes in $$\mathcal {N}=4$$ N=4 SYM
Abstract This article proves the cyclicity of anti-NMHV and $$\hbox {N}^{2}{\mathrm{MHV}}$$ N2MHV tree amplitudes in planar $$\mathcal {N}=4$$ N=4 SYM up to any number of external particles as an interesting application of positive Grassmannian geometry. In this proof the two-fold simplex-like struc...
