Dual conformal constraints and infrared equations from global residue theorems in N=4 SYM theory
Infrared equations and dual conformal constraints arise as consistency conditions on loop amplitudes in \Nf super Yang-Mills theory. These conditions are linear relations between leading singularities, which can be computed from the Grassmannian integral of N=4 SYM proposed recently.
Both dual conformal constraints and infrared equations are mapped explicitly to global residue theorems for 1-loop NMHV amplitudes. In addition, the identity relating the BCFW and its parity-conjugated form of tree-level amplitudes, is shown to emerge from a particular combination of global residue theorems.
