Group cohomology - of Alexey Beshenov
... Here f : G × G → L× , and σ(x) denotes the Galois action of σ on x ∈ L. A tedious verification shows that the associativity of the product above imposes the same associativity condition (3) on f as we have seen before. This construction leads to crossed product algebras (L/K, f). Two such algebras ( ...

On the sum of two algebraic numbers
... this result in the following symmetric form. Proposition 2 ([11]). If the triplet (a, b, c) ∈ N3 is sum-feasible and two particular numbers from the list a, b, c are coprime then the third number is the product of these two. See also [2], [7] and [8], where some conditions for the degree of α + β to ...
