Higher Labute-Serre duality and Lyndon words
Ido Efrat, Levav Ferber Tas
Let be a free profinite group on a finite ordered basis , and let , denote its lower -central filtration. There is a natural duality between $S…
Mild Pro- Groups and Ordered Monoids
Ido Efrat
We prove a criterion for the mildness of a finitely presented pro- group . It implies as a special case a cohomological mildness criterion via Massey products, generalizing r…
The Elementary Type Conjecture for Maximal Pro-p Galois groups
Ido Efrat
The Elementary Type Conjecture in Galois theory provides a concrete inductive description of the finitely generated maximal pro- Galois groups of fields containing…
Cofinality of Galois Cohomology within Purely Quadratic Graded Algebras
Tamar Bar-On, Ido Efrat
Let be a prime number. For a field containing a root of unity of order , let be the mod- Galois cohomology graded $\mathbb{F}…
Linking Invariants for Valuations and Orderings on Fields
Ido Efrat
The mod-2 arithmetic Milnor invariants, introduced by Morishita, provide a decomposition law for primes in canonical Galois extensions of with unitriangular Galois gro…
The symbol length for elementary type pro- groups and Massey products
Ido Efrat
For a prime number and an integer , we prove that the symbol length of all elements of -fold Massey products in , for pro- groups of elem…
