The Isomorphic Description of Torsion Units in Commutative Group Rings over Fields with Positive Characteristic
نویسنده
چکیده
A full classification up to isomorphism of torsions in abelian group rings over an algebraically closed field of nonzero characteristic is given in the present article. Specifically, an explicit formula is established and so the problem is completely exhausted. This characterizing strengthens classical results in that aspect due to Chatzidakis-Pappas (J. London Math. Soc., 1991) and to the author (Hokkaido Math. J., 2000) plus (Glasgow Math. J., 2001).

Commutative Group Algebras
Let R be a commutative ring with identity. If G is a group, then one can form the group algebra of G over R which we shall denote by R[G]. One can then ask the basic question, how much information about the group G can be deduced from the F-algebra R[G]7 A slightly different formulation is to assume that G and //are groups with R[G] isomorphic to R[H] as /^-algebras and to ask what relations ex...
متن کاملA Note on Isomorphic Commutative Group Algebras over Certain Rings
Suppose G is an abelian group and R is a commutative ring with 1 of char(R) = 0. It is proved that if G is R-favorable torsion and RH and RG are R-isomorphic group algebras for some group H , then H is Rfavorable torsion abelian if and only if either inv(R) = ∅ or inv(R) = ∅ and R is an ND-ring. This strengthens results due to W. Ullery (Comm. Algebra, 1986), (Rocky Mtn. J. Math., 1992) and (Co...
متن کاملOn Symmetric Units in Group Algebras
Let U(KG) be the group of units of the group ring KG of the group G over a commutative ring K . The anti-automorphism g 7→ g of G can be extended linearly to an anti-automorphism a 7→ a∗ of KG . Let S∗(KG) = {x ∈ U(KG) | x∗ = x} be the set of all symmetric units of U(KG) . We consider the following question: for which groups G and commutative rings K it is true that S∗(KG) is a subgroup in U(KG...
متن کاملWitt rings of quadratically presentable fields
This paper introduces an approach to the axiomatic theory of quadratic forms based on {tmem{presentable}} partially ordered sets, that is partially ordered sets subject to additional conditions which amount to a strong form of local presentability. It turns out that the classical notion of the Witt ring of symmetric bilinear forms over a field makes sense in the context of {tmem{quadratically p...
متن کاملISOMORPHISM OF COMMUTATIVE GROUP ALGEBRAS OF p-MIXED SPLITTING GROUPS OVER RINGS OF CHARACTERISTIC ZERO
Suppose G is a p-mixed splitting abelian group and R is a commutative unitary ring of zero characteristic such that the prime number p satisfies p / ∈ inv(R)∪ zd(R). Then R(H) and R(G) are canonically isomorphic R-group algebras for any group H precisely when H and G are isomorphic groups. This statement strengthens results due to W.May published in J.Algebra (1976) and to W.Ullery published in...
