Eli Matzri (Bar Ilan) - Triple Massey products in Galois cohomology

http://www.math.bgu.ac.il/~matzrie/index.html

Let p be a prime number, F a field containing a root of unity of order p, and G_F the absolute Galois group. Extending results of Hopkins, Wickelgren, Minac and Tan, we prove that the triple Massey Product H^1(G_F)^3→H^2(G_F) contains 0 whenever it is nonempty. This gives a new restriction on the possible profinite group structure of G_F.
