Abstract

A number of features and applications of subleading-color amplitudes of N=4 SYM theory are reviewed. Particular attention is given to the IR divergences of the subleading-color amplitudes, the relationships of N=4 SYM theory to N=8 supergravity, and to geometric interpretations of one-loop subleading-color and NkMHV amplitudes of N=4 SYM theory.
