Abstract
For x an element of a field other than 0 or 1, we compute the order n Massey productsã(1âx)â1,xâ1,â¦,xâ1,(1âx)â1ã of nâ2 factors of xâ1 and two factors of (1âx)â1 by embedding P1â{0,1,â} into its Picard variety and constructing Gal(ks/k) equivariant maps from Ï1et applied to this embedding to unipotent matrix groups. This method produces obstructions to Ï1-sections of P1â{0,1,â}, partial computations of obstructions of Jordan Ellenberg, and also computes the Massey productsãxâ1,(âx)â1,â¦,(âx)â1,xâ1ã.
