DESCRIPTION:Coauthor: Enrico Herrmann<br><br>There has been a lot of progr
 ess in exploring new mathematical structures in N=4 SYM amplitudes: on-she
 ll diagrams and Amplituhedron in the planar sector\, and special propertie
 s of integrands beyond the planar limit.&nbsp\;I will review some of these
  developments and then focus how the similar ideas can be extended to N=8 
 supergravity amplitudes. As it turns out the singularity structure of supe
 rgravity amplitudes is very different and it exhibits some surprising feat
 ures at both UV and IR.
