SUMMARY:Graviton scattering and geometric bootstrap bounds - James Bonifac
 io (DAMTP)

DESCRIPTION:Scattering amplitudes of massive spin-2 particles generically 
 grow with energy and lead to violations of perturbative unitarity. One way
  to partially soften such amplitudes is with the infinite towers of partic
 les present in Kaluza-Klein theories. In this talk I will discuss this mec
 hanism of unitarization and how it leads to a bootstrap procedure\, analog
 ous to the conformal bootstrap\, that yields new constraints on the eigenf
 unctions and eigenvalues of Laplacian operators on closed Einstein manifol
 ds.
