Induced Hopf Galois structures and their local Hopf Galois modules [PDF]
The regular subgroup determining an induced Hopf Galois structure for a Galois extension $L/K$ is obtained as the direct product of the corresponding regular groups of the inducing subextensions. We describe here the associated Hopf algebra and Hopf action of an induced structure and we prove that they are obtained by tensoring the corresponding ...

Galois module structure of Galois cohomology and partial Euler-Poincare characteristics [PDF]
Let F be a field containing a primitive pth root of unity, and let U be an open normal subgroup of index p of the absolute Galois group G_F of F. Using the Bloch-Kato Conjecture we determine the structure of the cohomology group H^n(U,Fp) as an Fp[G_F/U]-module for all n in N.

Galois theory of module fields
This thesis is about Galois theory.The development of a Galois theory for differential equations analogous to the classical Galois theory for polynomial equations was already an aim of S. Lie in the 19th century. The first step in this direction was the development of a Galois theory for linear differential equations due to E. Picard and E.

Frobenius modules and Galois representations [PDF]
Frobenius modules are difference modules with respect to a Frobenius operator. Here we show that over non-archimedean complete differential fields Frobenius modules define differential modules with the same Picard-Vessiot ring and the same Galois group schemes up to extension by constants.

Galois modules arising from Faltings's strict modules [PDF]
Suppose O is a complete discrete valuation ring of positive characteristic with perfect residue field. The category of finite flat strict modules was introduced recently by Faltings and appears as an equal characteristic analogue of the classical category of finite flat group schemes.

Scaffolds and generalized integral Galois module structure [PDF]
Let L/K be a finite, totally ramified p-extension of complete local fields with residue fields of characteristic p>0, and let A be a K-algebra acting on L. We define the concept of an A-scaffold on L, thereby extending and refining the notion of a Galois scaffold considered in several previous papers, where L/K was Galois and A=K[G] for G=Gal(L/K ...

Invariance of recurrence sequences under a galois group
Let F be a Galois field of order q, k a fixed positive integer and R=Fk×k[D] where D is an indeterminate. Let L be a field extension of F of degree k. We identify Lf with fk×1 via a fixed normal basis B of L over F. The F-vector space Γk(F)(=Γ(L)) of all
