The Kernel Unipotent Conjecture and the vanishing of Massey products for odd rigid fields
Jan Minac, Nguyen Duy Tan, Ido Efrat
A major difficult problem in Galois theory is the characterization of profinite groups which are realizable as absolute Galois groups of fields. Recently the Kernel -Unipotent C…

Filtrations of free groups as intersections
Ido Efrat
For several natural filtrations of a free group S we express the n-th term of the filtration as the intersection of all kernels of homomorphisms from S to certain groups of upper-t…

The Zassenhaus filtration, Massey Products, and Representations of Profinite Groups
Ido Efrat
We consider the p-Zassenhaus filtration (G_n) of a profinite group G. Suppose that G=S/N for a free profinite group S and a normal subgroup N of S contained in S_n. Under a cohomol…
