DESCRIPTION:Four-dimensional supersymmetric type II string theory vacua ca
 n be described elegantly in terms of pure spinors on the generalized tange
 nt bundle T+T. This leads to constraints on M6 involving Hitchin's "genera
 lized complex geometry".\n\nIn this talk\, we apply the same techniques to
  any ten-dimensional supersymmetric solution\, not necessarily factorized 
 as AdS4xM6 or Mink4xM6. I will describe a system of differential equations
  in terms of forms describing a generalized ISpin(7) structure is equivale
 nt to unbroken supersymmetry\, in both IIA and IIB. One of the equations i
 n the system reproduces in one fell swoop all the pure spinors equations f
 or four-dimensional vacua.\n\n
