"Color-Kinematic Symmetry and Gauge-Gravity Connection in the Space of Generalized Propagating Matrix and in Light-Like gauges"
 Slideshow (PDF)
There have been major advances in our understanding of scattering amplitudes in gauge theories and in gravity. Aside from great improvements in computational proficiency, there are hidden symmetries which connect color with kinematics. Furthermore, gauge amplitudes and gravity amplitudes are connected. We shall review these results and set up a formalism, by which such symmetries are systematically enforced and their immediate consequences become transparent. Generalized gauge freedom and interplay between color and kinematics will have a natural setting.
