Equivalence Theorems and Hopf–Galois Extensions

Journal of Algebra, 1997
This work studies equivalence theorems for categories \({\mathcal M}(H)^D_A\) of right (\(D\)-\(A\))-Hopf modules. The authors get a characterization of the Hopf-Galois extensions. The paper has three main parts. In section two the notions which are going to be used are defined and some of the theorems relating the category of modules over a ring and ...

Characterization of Group of Invertible Elements of Six Index Zero Completely Primary Finite Rings of Characteristic p

Wasit Journal for Pure Sciences
The study of finite extension of Galois rings in the recent past have given rise to commutative completely primary finite rings that have attracted much attention as they have yielded important results towards classification of finite rings into well ...

The Projective Character Tables of a Solvable Group 26:6×2

International Journal of Mathematics and Mathematical Sciences, 2019
The Chevalley–Dickson simple group G24 of Lie type G2 over the Galois field GF4 and of order 251596800=212.33.52.7.13 has a class of maximal subgroups of the form 24+6:A5×3, where 24+6 is a special 2-group with center Z24+6=24. Since 24 is normal in 24+6:

Cuspidal ${\ell }$ -modular representations of $\operatorname {GL}_n({ F})$ distinguished by a Galois involution

Forum of Mathematics, Sigma
Let ${ F}/{ F}_0$ be a quadratic extension of non-Archimedean locally compact fields of residual characteristic $p\neq 2$ with Galois automorphism $\sigma $ , and let R be an algebraically closed field of characteristic $\ell ...

On Rational Distance Point Problem for Quadrilaterals

四川大学学报. 自然科学版, 2016
In the present paper, by pointing out some errors in reference [17], we know that the well-known integer distance point problem of Steinhaus is still open. Using the result of Galois extension, we discuss the Steinhaus problem for some quadrilaterals. In

Skew-Forms and Galois Theory

Comptes Rendus. Mathématique
Let $L/K$ be a cyclic extension of degree $n = 2m$. It is known that the space $\mathrm{Alt}_K(L)$ of alternating $K$-bilinear forms (skew-forms) on $L$ decomposes into a direct sum of $K$-subspaces $A^{\sigma ^i}$ indexed by the elements of $\mathrm{Gal}
